Hi,
bEndpointAddress = 135, is the interrupt endpoint. It is not the failing
one.
Can you try to put the break on "return -EPIPE" one line back?
Also, you probably need to run "pwcview" to trigger the open of those
failing endpoints.
When you catch it send me the dump of *uhe.
BTW: Do you have IRC? Maybe it would be faster to meet there and debug :-)
