I went to install some new software on my Visor yesterday and got a
rude surpise, as my system froze hard (unpingable, no response to
keyboard or mouse, no oops).  A bit of experimenting shows:

It works fine with usb-uhci in all versions I tested.

Plain 2.4.2 works fine with either usb-uhci or uhci.

On ac12 and 13 if the visor driver is compiled into the kernel it will
work poorly for a time (very slow sync, jpilot/pilot-link complains of
"weird packet" or "timeout") and then quit, refusing to even register
when the device connects.  Once this happens, after hitting the "sync"
button the pda just sits and eventually times out, saying it failed to
connect to the desktop.

If I compile the driver as a module on ac12 and 13 it will hang the
system on module unload after a failed attempt to install software to
the pda.  Normal syncs may work, but installing 3-4 files will hang
the system every time.  Since the Visor only registers as a USB device
for the duration of the transfer this hangs the system as soon as the
sync attempt quits.

In no case do I get any error messages in the logs, no console
messages, and no oops.

This isn't a critical issue, as the usb-uhci driver works fine, but
the uhci driver is the default.  Still, hanging the system is
misbehavior.

I also noticed that selecting to statically compile usb serial
adapters, then selecting module for the Visor driver wouldn't compile
the Visor module.  As long as the usb serial and Visor were both set
the same (either static or module) it compiles fine.

I'd be happy to test patches, or step back through the 2.4.2-ac series
to find exactly where things broke (but the changelog below shows a
change to the visor in 2.4.2-ac12).


Thanks,
Erik
