Hello, I think I've got it ... previouusly my endpoints were misconfigured but after reading up on the mailing list over at libusb i *think* i've figured out what was missing.
This is what was in my /proc/bus/usb/devices before : T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 8 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=16b4 ProdID=0103 Rev= 2.12 S: Manufacturer=Licensed to Code, LLC S: Product=My Source/Sink Product S: SerialNumber=gpuyb82dkhtsb9z2ten9ezvmc21prls1g3qib5r8fbdwhz8az01w5mcm8d36xip C:* #Ifs= 1 Cfg#= 3 Atr=c0 MxPwr= 2mA I: If#= 0 Alt= 0 #EPs= 0 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none) ^ No endpoints. I missed out a few things in the usb.c sample file - mainly missing configurations for HS endpoints. Here's what's there after I realized what I had done wrong : T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 8 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=16b4 ProdID=0103 Rev= 2.12 S: Manufacturer=Licensed to Code, LLC S: Product=My Source/Sink Product S: SerialNumber=qbyjcna1c6qycetx7qvlr61meata7ya25dbfnxtr4h7oifoukdemu2y30nn8wda C:* #Ifs= 1 Cfg#= 3 Atr=c0 MxPwr= 2mA I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none) E: Ad=81(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=125us E: Ad=83(I) Atr=03(Int.) MxPS= 8 Ivl=4ms ^ Yay! Endpoints to work with! Hopefully things will go smoothly from here onwards. :) Lisa > Hello, > > A while back I asked a bunch of newbie questions and they were answered. > Thankyou very much.
