Dotaz: Lze "pošťouchnout" detekci HW v NetworkManageru/nm-appletu?

[Ladislav Nešněra]

Když připojím externí USB 3G modul ("palec" od T-Mobile/O2), tak mám někdy mobilní síť k dispozici za pár sekund, jindy za pár minut. Máte někdo tip, jak počítač pošťouchnout, když si dává na čas? (Linux 3.11.9-200.fc19.x86_64 tj. Fedora 19). Díky

A v dmesgu se objeví rovnou?

Já mám integrovaný 3G modem a on se nějakou dobu inicializuje, než se doptá na PIN... (ale teda ne několik minut)

[mirek]

Může to být pár minut.

[Jendа]

Mně to brzdí usb-modeswitch, většinou to trvá tak půl minuty. Koukej do dmesg, nejdřív se objeví CD mechanika, pak ttyUSB. NM laguje až po objevení ttyUSB nebo je chyba předtím? Taky to jde modeswitchnout ručně, já mám nějaký Huawei a tam to je usb_modeswitch -v 12d1 -p 14fe -m "0x01" -M "55534243123456780000000000000011062000000100000000000000000000" -I

Problem je i bez mode-switch. Ted jsem to zkousel s Nokii E51 v SysRecCD.

1. vypojeni kablu z modemu a zapojeni /dev/ttyACM se vytvori hned

2. v/z nmcli dev je stejne rychle jak applet oboji se ukaze presne po 50s.

3. ovladac v poradku, applet v poradku. network-manager je problem.

[MadCatX]

Co je to přesně za modem? Některé z těchto zázraků mají rozhraní, která se navenek tváří jako sériová, ale nejsou. To dokáže ovladač zmást, což se projeví právě dlouhou detekcí modemu. Pro Huawei E1750 by to mělo být fixnuté (http://www.spinics.net/lists/linux-usb/msg94619.html). Jestli má váš modem jiné PID, možná bude třeba patch pro "option" ovladač v jádře.

[jadd]

to me pobavilo, ovladac premysli jak clovek, je to ten modem nejsem si jist ale me premysleni uz trva dlouho tak ja mu to uz vratim aby mi nenadaval. Nebo to je neodladenym kodem?

[MadCatX]

Předpokládám, že ovladač zůstane viset v usb_wwan_open() a než to vytimeoutuje, modem není v NM dostupný.

[Ladislav Nešněra]

Konkréní zařízení? Asi bude nejlepší odpovědět výpisem, protože systém sám "váhá" idProduct=1446 x idProduct=1001.

I ten můj model má v sobě čtečku na microSD (nevyužívám). Rozhodně mě pobavilo, že v odkazu synek řeší 7s. To bych považoval za velký úspěch

Chování asi odpovídá tomu, co píše Jenda - musí se to vyblbnout s CD-ROM, než se toho chopí NM

Teď bych docela uvítal BFU radu, kudy dál

[MadCatX]

PID 1446 bude nejspíš ID před modeswitchem, 1001 po modeswitchi. Z toho odhaduji, že jde o Huawei E1550? Co řekne o modemu lsusb -v? Ten modem se zjevně nechová zrovna podle USB specifikací, s čímž se nedá nic dělat, ale alespoň simulovanou CD-ROM a SD čtečku by mělo být možné nechat ignorovat.

[Ladislav Nešněra]

K mé radosti máme po "zábavě". Před chvílí jsem aktualizoval na Linux 3.11.10-200.fc19.x86_64 a všiml si, že upgrade se dotkl i usb_modeswitch (byť asi rozhodující je novější kernel). Teď je modem Huawei E1750 připraven během chvilky a v dmesgu má idProduct=1446. Pro zajímavost přikládám aktuální výpis, který začíná přehozením z jednoho USB do druhého a končí, když už jsem byl na Netu.
