I’m trying to provide USB camera support under QNX4. I’ve compiled the cpia
driver (that was included in 001019.usb_sdk.tar, but not subsequently
released) with the latest DDK libs (010207). cpia_insertion() gets called,
but the usbd_attach() call never returns. The drivers end up looking like
this (sin):
2 16574 //22/bin/devu-uhci 15r RECV 0 38k 159k
2 16578 //22/bin/devu-uhci 15r REPLY 16574 38k 159k
2 16869 //22/bin/devu-cpia 15r RECV 0 22k 114k
2 16872 //22/bin/devu-cpia 15r REPLY 16574 22k 114k
I’ve included the ‘usb -vvv’ output below.
Any help would be greatly appreciated. Thanks.
