I just bought a USB serial device that is supposedly supported by
It does recognize it, but when I try to access it in any way, the kernel
locks up my entire system. Actually, I take back the 'in any way'.  When I
change ownership on /dev/usb/ttyUSB0 to me instead of root, and try to use
pilot-link, it locks up when I press the hotsync key on my Palm Pilot.
usbview reports: Vendor ID: 06cd  Product Id: 0103
When the usb-serial is loaded into the kernel, the product id mysteriously
changes to 0104.

Comment 1 Omnifarious 2000-10-24 03:10:04 UTC
Oh, yes...  My kernel is custom.  I compiled LVM and reiserfs into it (and
disable the MD devices completely).
I tried getting the latest keyspan code, but the 2.4 USB stuff is different from
the backport in RH 7, so it won't compile.

Comment 2 Alan Cox 2000-10-27 16:20:26 UTC
The 103 /104 thing is right (without/with firmware downloaded)

The rest sounds like general 2.4 kernel problems and its probably best to send
the report to the 2.4 USB maintainers directly.
