I did go and explicitly unbind the device from any drivers (it was 
apparently bound to 'usb'...) and still no go.  I unloaded any and all 
spurious USB device modules that were loaded.

usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd usbhid-ups rqt 128 rq 6 len

usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd usbhid-ups rqt 129 rq 6 len

 1-1: usbfs: USBDEVFS_CONTROL failed cmd usbhid-ups rqt 128 rq 6 len 255

Those last two are after I unbound the device from 'usb'...

For the record, have I yet mentioned that

- The device in question is a "Pepper Pad 2", powered by a 624MHz pxa270 
XScale CPU (arch armv5tel)
- Linux distro is mostly MontaVista Linux 3.1, a mixture of CEE and Pro 
packages, but with kernel 2.6.13.4
- The PXA270 only does USB 1.1
- System doesn't use udev or hotplug, so everything is running as root.  
Also some /dev/ entries seem to be missing, for example there is no 
/dev/usb/* - I had to manually create /dev/ttyUSB0 just to use my USB to 
serial adapter
- I am totally willing to chalk this up to "weirdness" and use my Belkin 
USB to serial port adapter, if it weren't for the fact that so far I'm 
doing everything right and it's not working :(

Thanks for everyone's suggestions too.
