	Not sure about this; actually, I'm in pretty much the same boat as
Akira (USB cradle, Visor Platinum, etc. -- only difference is that I have
4.2-STABLE from a CVSup from 9 days ago, but I experienced the same problems
with RELEASE).    

	I'm getting the same error messages as Akira (though the exact error
mesgs I get vary with the vesion of ColdSync). 
	I can't get to my computer for now, so I can't be too detailed here,
but I can tell you this much:

USB works with this kernel, at least as far as downloading from the device
is concerned.  I can't seem to get coldsync to work at all from the command
line, but if I set up this in usbd.conf:

device "Handspring Visor"
        devname "ugen0"
        vendor 0x082d           
        product 0x0100          
        release 0x0100
        attach "/usr/local/bin/coldsync -t usb -p /dev/ugen0 -mb
/usr/home/james/.palm/backup"

...the handspring *does* backup all of its databases into that backup dir.
From this I'm guessing that USB input and output works, because the
handspring had to get the command from the PC to do a pdb backup.  Also, my
PCI USB card shows up in dmesg:

uhci0: <VIA 83C572 USB controller> port 0xf400-0xf41f irq 15 at device 13.0
on pci0
usb0: <VIA 83C572 USB controller> on uhci0
usb0: USB revision 1.0
uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered

....and at every push of the hotsync button, 3 lines get added at the bottom
of the dmesg. I don't have access to it now; something like :

ugen0: Handspring Visor (c)2000 attached
[something else]
ugen0: visor detached

	Besides that, I've had permissions on /dev/ugen* and /dev/usb* set
to rwxrwxrwx (what the hell; I'm the only one using it ;)

	I'll reproduce the errors and follow the instuctions you gave Akira
when I get back to my box.

	All the required USB support for non-USB developers seems to be in
GENERIC:
device          uhci            # UHCI PCI->USB interface
device          ohci            # OHCI PCI->USB interface
device          usb             # USB Bus (required)
device          ugen            # Generic

Can't answer that; my visor is my only USB device at present.

	That's all for now
LLAP,
