no usbview ele aparece como unknown device ligado ao
VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (#3)
O que eu estou achando estranho é que há referências a uhci e a ehci. No meu kernel
está configurado o uhci builtin e o ohci e ehci como módulo. estou pensando em desativar
dois e deixar só um. o ohci vai voar, mas qual dos outros dois eu tiro? o ehci ou o uhci???
Paro por aqui, Fred
