On a PXA263 based system with an isp1161 and your driver from January 31, I tried to copy big files from a USB stick in one port to another stick in the second port. The copy always hang and, according to the PTD trace which looks similar to Ian's, the same transfer was submitted continuously but the chip seemed to never handle it (CC=f ACT=1). At first I suspected an electrical problem because waiting for the clock to lock after a SW reset always fails on this board. For now the check for the clock is disabled and, with the version of your driver you just posted, I was able to copy 100MB of data from one stick to the other. Also, insertion and removal of USB devices and of the isp116x-hcd module seem to work flawlessly now.
