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 :-)
