Ahoj, chcel by som sa ta opytat ci pouzivas s tymto router bordom aj nejake externe storage medium ako SD kartu alebo nejaky usb klucik ak ano, ci s nimi nemas nejake problemi. Bo ja mam taky problem ze ked skusam pouzit ako storage SD kartu alebo usb kluc tak mi pri pokuse o zapis(vytvaranie FS, velkeho suboru) zacne davat do dmesg i/o errory, v dmesgu to vyzera tak ze akoby pocas zapisu odpojil usb nieco som googli a vyzera to na chybu usb2.0 drivera(kmod_ehci). pouzivam sd kartu 16gb kingstone class4 karta je uricte dobra v inych strojoch ide ok. Skusal som stable openwrt backfire aj trunk testing release openwrt v obydvoch pripadoch sa deje to iste. dik moc gus

toto je chyba ktoru mi pise do dmesg:
