Command timeout, abortPipe causes crash

Hi,

My device occasionally times out USB control pipe transaction. I have increased the guard time for these transactions to no avail, the transactions do not complete. At this time, I am not sure whether the problem is the device itself or a problem with the driver. Anyway, after the transaction times out, I call abortPipe() to cancel the transaction. The call to abortPipe() on pipe 0 causes a memory fault. I'm trying to find out why.

I've downloaded the 1.8.7 USB Development kit, installed the package, and followed the instructions in the readme file including executing the shell commands to move the new .kext files. I'm trying to view the USB log with the usblogger tool and get an error "Could not set up notification port (10000003)". Is something else required to get the usblogger working?

Paul
