Hi to all.My previous experience with USB was PIC 18F4550 and HID device so
sorry if I ask something obvious.
I have a problem with AVR32 UC3A0512 device and Vendor class. Hardware is
EVK1100 clone (WaveShare EVK3A).
I manage to build firmware with AtmelStudio 6 and install driver (libUSBwin32
or libUSBK). Device is visible by
Windows without any warning. When I try xusb.exe from example folder my device
is listed with two interfaces
(0 without endpoints and 1 with two endpoints: interuput and isochronous). In
my host PC application when I try
to set active interface 1 I got error (from UC3A debug printout message is
USB_REQ_TYPE_STANDARD). From what
I read my host app must activate Vendor device by sending USB_REQ_TYPE_VENDOR
request with appropriate alt
configuration number? Is there any Vendor class example firmware for EVK1100 to
test libusbx functionality?
Identical results are with composite Vendor+HID device (HID part can be opened
and send/receive data).
