Dotaz: Převodník HDMI do USB 3.0

[Daniel]

Dobrý den. Mám Ubuntu 16.04 64bit. Koupil jsem si tento převodník z HDMI do USB. Můj notebook má jen USB 2.0. Po připojení funguje:

Jenže abych z něj dostal FullHD, potřeboval jsem rychlé USB3.0. Koupil jsem tedy tuto kartu.

Na  zkoušku jsem připojil myš a fungovala.

Připojil jsem tedy HDMI převodník, ale ten nefunguje:

Co s tím? Za rady moc díky.

Odpovědi

[dustin]

Zkusil bych upgrade kernelu na co nejnovější, s USB3 a jeho LPM byly problémy.

[Daniel]

Díky za tip. Tak jsem zaktualizoval z jádra 4.4 na 4.8, ale chová se to stejně. Máte ještě nějaký nápad?

[iwk]

Pod inym os (rozumej z rodiny okienok) to funguje? Zistit, ci je to problem medzi tymi dvoma zariadeniami alebo nie.

[Daniel]

Bohužel to nemám možnost nikde zkusit.

[pc2005]

Nešla by nainstalovat nějaká trial verze?

aha, nupaci, rec byla o windows ktere instalaci v 30day trial bezne (>=7) podporujou...

[Pavel 'TIGER' Růžička]

Také jsem pořídil podobnou kartu a byl s ní problém, problém se vyřešil, avšak karta je vhodná pouze na nenáročný odběr proudu, jako mají flashdisky. Při zapojení něčeho náročnějšího, jako je třeba externí vypalovačka, zařízení nebude fungovat.

[Daniel]

No u toho je ještě nějaký USB kablík s jackem.. že by to bylo dodatečné napájení?

[j]

Mno ... USBcko ti bez komunikace da 100mA ... s komunikaci 500mA. Je klidne mozny, ze ta karta to proste neda. Sloucit 2 USBcka by ti pak mozna ani nepomohlo - ziskal bys tech 100mA navic. Pisou tam, ze to chce 2,5W, coz je tech 500mA. Takze leda externi napajeni.

Mimochodem, USB2 da 30MB/s zcela realne (teoreticky dvojnasobek), coz ti na HD musi stacit naprosto vpohode. Nejvetsi h264 co mam na disku ma 30Mbit, coz je necely 4MB/s. Trojku na to vazne nepotrebujes.

[dustin]

Pokud jsem to dobře pochopil, ta karta příchozí dekomprimované video z HDMI nijak nekomprimuje, po USB běží yuv raw pixely, jen zabalené do UVC formátu.

[Daniel]

Přesně tak. Ps: Jinak ten Jack s USB na druhém konci je u té karty.

[j]

V tom pripade to nemuze fungovat, protoze nekomprijmovany 1920x1200 (coz tam uvadej) pri 60FPS pres USB3 neprotlasis ani kdyby ses na hlavu stavel a usima odstrkoval.

[pc2005]

Tak píšou max 1080p/60, ale zase 1900*1200*60*24 = 3.3Gbps a USB 3.0 má 5 Gbit/s to na stavění na hlavu není (nejspíš to reálně nedá, ale je to ochlup). A pokud by to byl nějaký ztrátový YUV, tak tomu stačí ještě míň.

[Daniel]

Tak pořád na tom budu lépe než s USB 2.0:) Jinak ani to napájení karty z externí USB nabíječky nepomohlo. Ty chyby jsou opravdu kvůli nedostatečnému napájení?

[dustin]

Dle warningů v dmesg http://lxr.free-electrons.com/source/drivers/usb/host/xhci-ring.c a podobných problémů reportovaných na netu to zařízení neodpovědělo. Důvodů může být samozřejmě víc, opravy/změny v tom xhci driveru taky.

Pokud nepomohlo posílené napájení, pak by to opravdu chtělo na stejném HW otestovat v jiném OS, nejlépe v oficiálním podporovaném, tedy windows. Asi to ale nepůjde z live distribuce...

[Pavel 'TIGER' Růžička]

Tyhle USB 3 karty mají problémy s power managementem, pokud ho lze v Biosu/UEFI vypnout, vypni ho. Viz můj odkaz, který jsem zde už postnul.

[pc2005]

Ale zase podle výpisu lspci to vypadá, že je PME-Enable vyplý (jestli to je teda dostatečná podmínka pro vypnutí). Rozhodně bych to ověřil v BIOSu (nastavuje se to pro ten ExpressCard slot, tu kartu ani HDMI ten BIOS nejspíš nepochopí ).

[pc2005]

Jaký máš notebook?

Hodil by se výpis (vypíše to mód PCIe linek karty a bridge, informace o čipsetu, použitý kernel driver pro ExpressCard):

lspci -vvnn

Taktéž by se hodil výpis připojeného HDMI přes USB 2.0 a přes ExpressCard adaptér, možná s nějakým USB zařízením v tom adaptéru:

lsusb -vv

Převodník teda na normálním USB 2.0 funguje? Jaké rozlišení jsi zkoušel (z těch co na USB 2.0 fungují)?

Myš není moc dobrý nápad. Jedna USB myš co tady mám jede jen na low speed usb 1.0, což je úplně někde jinde. Ideální by bylo jiné usb 3.0 zařízení nebo aspoň usb 2.0 (třeba flashka, čtečka, webkamera!).

Připojuješ převodník se zapojeným HDMI nebo naprázdno? Vyzkoušel jsi obě varianty?

Jaký kabel používáš na připojení toho HDMI do počítače. USB 3.0 vyžaduje speciální kabel, ten konektor je s USB 2.0 zpětně kompatibilní, ale pro 3.0 mód má navíc další dráty v sobě. Je v pořádku kabel? Není moc dlouhý? Mám pár USB 2.0 zařízení, co na moc dlouhým USB kabelu odmítaj fungovat. To se obvykle projevuje náhodnými "can't read configurations, error" a nebo timeouty. Pokud jsi nejsi jistý zda to je fakt USB 3.0 kabel, tak udělej foto vnitřku konektoru (měly by tam být staré piny + nových 5).

BTW Na tom fotu toho HDMI: nezdá se vám že je v tý krabičce USB host konektor? Neměl by tam být spíš device? Teda ledaže by šlo USB 3.0 zapojovat každej s každým...

P.S. Jen tak, kdyby se v tom někdo chtěl hrabat:

[ 1677.160714] usb 4-2: can't read configurations, error -71

-71 je EPROTO (chyba protokolu) ... ale nejspíš to je vyústění těch chyb předtím.

[Daniel]

Přílohy:

• lspci_vvnn (37658 bytů)
• lspci_vv_2_hdmi (36800 bytů)
• lspci_vv_3_hdmi (36800 bytů)

Tak, zkusím to vzít popořade.

Používám modrý USB 3.0 kabel, který byl součástí dodávky HDMI převodníku.

Výpis lspci -vvnn bez připojeného zařízení do USB 3.0 karty v příloze lspci_vvnn.

Výpis lspci -vv s připojeného zařízení do USB 3.0 karty v příloze lspci_vv_3_hdmi

Výpis lspci -vv s připojeného zařízení do USB 2.0 v ntb v příloze lspci_vv_2_hdmi

Rozlišení videa se mi na USB 2.0 automaticky (v cheesee nebo OBS) nastavi na 1280x720 a funguje plynule. Mohu nastavit až 19020x1200, ale to už se strašně seká.

HDMI převodník není v USB 3.0 funkční ani "naprázdno". Viz. dmesg s chybami v mém prvním příspěvku. Není podle mě tedy podstatné, jaké HDMI zařízení do něj připojím, nicméně zkouším foťák Sony Alpha-5000 a akční kameru EX5000.

 

Moc děkuji za snahu mi pomoct.

Ještě doplním, že připojení webky přes USB fnguje:

Pozor psal jsem "lsusb -vv" ne "lspci -vv" (ten už je zahrnutej jako podmnožina toho "lspci -vvnn").

1280x720

Je to opravdu 60Hz? Aby se nevynechávaly snímky. Na USB 2.0 máš jak tady někdo podotknul maximálně tak 30MBps (možná víc, pokud je sám na řadiči a je to jen jedním směrem). Pro 1280x720 to odpovídá tak 300 pro FPS*bpp. Což by mohlo být tak 30fps a 12bpp (což je v RGB hnus), nebo nějaký komprimovaný YUV (kterej to je by ukázal ten nahrávací software - ideálně třeba mplayer nebo "v4l2-ctl --all" a právě by to nejspíš šlo vyčíst z toho lsusb -vv).

Nicméně vidím jeden problém zde:

03:00.0 USB controller [0c03]: ASMedia Technology Inc. ASM1042 SuperSpeed USB Host Controller [1b21:1042] (prog-if 30 [XHCI])
	LnkSta:	Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-

Vypadá to že tvůj čipset (podle jednotlivých "PCI bridge [0604]: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port") umí maximálně PCIe 1.1, takže ta ExpressCard PCIe 2.0 karta sice fungovat bude, ale nedosáhne maximální rychlosti USB 3.0. To by teoreticky vadit nemělo při enumeraci USB zařízení, ale zrovna UVC je dost fujtajbl na enumeraci . Jinak to samozřejmě nebude fungovat pokud budeš chtít přenos plnou rychlostí USB 3.0 (resp cokoliv mezi 250MBps až 500MBps). Stejné rozlišení, co fungovalo po připojení na USB 2.0, by ale mělo fungovat. To můžeš otestovat tím, že připojíš ten HDMI přes obyčejný USB 2.0 kabel do té XHCI karty.

Potvrzení z wikipedie:

On some old (2009–2010) Ibex Peak-based motherboards, the built-in USB 3.0 chipsets are connected by default via a 2.5 GT/s PCI Express lane of the PCH, which back then did not provide full PCI Express 2.0 speed (5 GT/s), so it did not provide enough bandwidth even for a single USB 3.0 port.

Ještě jsem v jedné diskuzi našel link_quirk parametr pro xhci_hcd, takže pokud más xhci-hcd jako modul (je zobrazenej jako "xhci_hcd" v lsmod výpisu), tak ho rmmodni a pak ho načti s parametrem:

modprobe xhci-hcd link_quirk=1

V případě že je ten modul v kernelu, tak by mělo fungovat přidat do kernel cmdline něco jako:

xhci_hcd.link_quirk=1

Ale přesnou syntaxi hádám (+ někde se v kernelu používá podtržítko a na jiném místě pomlčka).

[Daniel]

Moje nepozornost. Ještě tedy doplňuji lsusb -vv. Jinak v modulech xhci-hcd nemám.

Spíš jsem teda myslel výpis toho HDMI (thle je virtuální root hub), když je zapojenej do USB 2.0 (jestli nemá nějakou rozbitou konfiguraci).

Jinak jestli teda není ve výpisu modulů xhci-hcd nebo xhci_hcd tak by ten kernel command line parametr měl být podle wikipedie:

xhci_hcd.link_quirk=1

nebo

xhci-hcd.link_quirk=1

ale spíš to první. Ale i když tam dáš současně obě, tak by to nejspíš nemělo vadit, tu chybnou to bude ignorovat.

Víš jak přidat kernel command line parametr u tvého distra? (u lilo to snad jde i přímo ručně napsat do bootovací konzole, u grubu myslím taky).

pro Ubuntu ktere ma, kde je Grub2 je to nasledujici:

- docasna zmena, pri (uplnem zacatku) startu zmacknout jakoukoliv klavesu, zobrazi se manu, zmacnout e jako edit, najet na radek zacinajici linux a vkladat mezi quiet a splash

-trvala zmena, v souboru /etc/default/grub zmenit radek:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

na

GRUB_CMDLINE_LINUX_DEFAULT="quiet xhci_hcd.link_quirk=1 splash"

a aplikovat zmenu regenerovanim grub menu pomoci:

sudo update-grub

Tak s těmi parametry se to chová stejně:

Ještě je otázka zda byl formát těch kernel parametrů správně. Kdyžtak to zkus ověřit přes:

find /sys/module | grep uhci | grep parameters

To by mělo najít soubor "link_quirk", jehož obsah by měl být "1". Pokud bude "0", tak ty kernel parametry xhci driver nedostal.

Teď jsem si ale všimnul tohodle:

    wSpeedsSupported   0x0008
      Device can operate at SuperSpeed (5Gbps)
    bFunctionalitySupport   3
      Lowest fully-functional device speed is SuperSpeed (5Gbps)

To je dost divný. Podle USB 3 specifikace by to mělo podporovat jen a pouze superspeed zařízení (tedy žádný fullspeed a highspeed). Bylo v XHCI zapojeno něco když jsi pouštěl ten lsusb -vv příkaz?

Koukal jsem se do zdrojáků kernelu a ASMedia má nefunkční bulk stream přenosy. To by ale v případě "webkamery" nemělo vadit, ta používá isochronní. Stejně by se ale hodil ještě jeden výpis pro stav:

• Připoj do obou portů XHCI nějaké USB 2.0 nebo 1.1 zařízení, například flashku, myš.
• Připoj do normálního USB 2.0 portu HDMI převodník.
• Ověř že se flashka, myš a HDMI detekují (reaguje na myš, objeví se nový disk, detekuje se nová webkamera).
• Proveď "lsusb -vv" a kompletní výpis hoď sem (chci vidět jaké deskriptory má ten HDMI a co se stane při připojení zařízení s deskriptory toho XHCI root hubu).

P.S. Ten HDMI jsi doufám zkoušel v obou portech toho XHCI? P.P.S. Pokud ani tenhle pokus nezachytí žádný problém, tak už asi zbývá:

• Náhodně nastavovat bity v "quirk" parametru xhcd driveru (quirks=0x1ffffff, každý bit je jedna "oprava" hw chyby řadičů)
• Povolit debug výpisy z xhcd driveru a založit kernel bug (tyhle lsusb/lspci/dmesg výpisy se ti budou hodit do diskuze)
• Prohlásit XHCI kartu za vadnou, reklamovat (nefunkčnost na 5Gbps je u XHCI docela velký problém, ale chtělo by to ověřit s jiným XHCI zařízením :-/) a používat maximálně rychlosti USB 2.0 :-/

[pc2005]

Knihovna pro kinect (což je vlastně taky taková webkamera).

Intel and NEC USB 3.0 host controllers are known to work. ASMedia controllers are known to not work.

[Daniel]

Tak až to zadám do zavaděče z - nebo _, vždy mám jen tenhle výstup:

# find /sys/module | grep uhci | grep parameters
/sys/module/uhci_hcd/parameters
/sys/module/uhci_hcd/parameters/ignore_oc
/sys/module/uhci_hcd/parameters/debug

Zapojil jsem fkashku do USB3.0 karty a funguje. Do USB2.0 jsem připojil převodník a také funguje.

Tak až to zadám do zavaděče z - nebo _, vždy mám jen tenhle výstup:

Kruci já blbec tam nechal uhci (mám akorát USB 1.0 a 2.0), mea culpa má to být:

find /sys/module | grep xhci | grep parameters

Hmm tak podle toho výpisu mám obavu, že i pokud by byla USB 3.0 enumerace v pořádku, tak to tvé požadavky nesplní. Za předpokladu, že máš opravdu vyvedenou PCIe 1.1 na ExpressCard, tak ta má přenosovku 250MBps a pro rozlišení 1920x1200 je rychlost při 60fps (dwFrameInterval[0] = 166667*100 ns):

dwMaxBitRate                2211840000

Což odpovídá 276MBps (ale ještě se posílá nejrůznější komunikace pro USB řadič a audio a protokolové overheady). Takže budou vypadávat některé framy.

Samozřejmě to nemění nic na tom, že při 30fps by to mělo fungovat určitě (cca 138MBps, to téměř dá i starý PCI) a to, že by se to mělo tak jako tak nadetekovat.

Zapojil jsem fkashku do USB3.0 karty a funguje.

Divný, podle podpory standardu z lsusb by to mělo umět jenom USB 3.0 ale asi maj jen chybu v oznamování toho co podporujou .
