Is anyone using fxload with the original ezusb (Anchorchips AN2131)?
I'm getting timeouts (-110) after the code is loaded, and switching the CPUCS 
register back to run mode.

/sbin/fxload -v -t an21 -D /proc/bus/usb/002/003 -I sunkbd_hid_kbdmouse.ihx 
microcontroller type: an21
single stage:  load on-chip memory

reset CPU
can't modify CPUCS: Connection timed out

The device disconnects, and never comes back - I have to unplug.

usbdevfs: USBDEVFS_CONTROL failed dev 2 rqt 64 rq 160 len 1 ret -110
usb.c: USB disconnect on device 00:01.3-2 address 2

I did a quick check of the EZUSB Tech Manual, and the command looks right (ie 
it really does have an A0 command for CPUCS).

Any ideas?
