sorry for disturbing you, I have got the problems with USB CDWRITER and it appears to be somewhere between KERNEL (UHCI versus USB-UHCI module) and CDRECORD. I send a description as an attachement - file "cdrecord-bug".
Thanks Martin
PROBLEM ------- CDRECORD freezes with HP CD-WRITER 8200e (external USB).
KERNEL version
--------------
* Currently 2.4.25, but same problem appeared on 2.4.21 and previous versions
* Also the same problem is with 2.6.3
BUT!!
* On 2.4.25 I use uhci.o module!!! usb-uhci.o CLEARED the problem!!!
CDrecord works with usb-uhci.o!
* On 2.6.3 I use uhci-hcd.ko and same problem appeares (uhci-hcd was derived
from uhci.o from 2.4.25).
