Estou tentando construir um módulo do kernel para usar umRalink RT5370Dispositivo USB Wi-Fi, com ID lsusb 148f:5370. Meu host é um NAS com kernel Linux baseado na versão 2.6.33.2.
Eu baixei as fontes do driver doSite da Mediateke estou praticamente na mesma situação descritaaqui; o módulo do kernel compilado rt5370sta.koparece carregar corretamente porque:
[/share/Public/ralink/alt] # insmod rt5370sta.ko
[/share/Public/ralink/alt] # dmesg -c

NVM is EFUSE
usbcore: registered new interface driver rt2870
Mas os problemas começam na hora de montar a interface, em especial aRTUSBBulkReceive: Falha ao enviar Rx URB -22mensagem:

Claro que não digitaliza e oultrapassagenscomece a incrementar:

Nesta situação, verificandodmesgnovamente leva a muitos desses-22erros:
