I am not subscribed to linux-hotplug, but am following this thread on
the list archive.
This is exactly the problem I am having with my Huawei E220 modem. (The
modem has a usb cdrom device with the Windows drivers.) The cdrom
emulation on the device is broken, so userland attempts to mount the
device trigger a device reset.
The network operators don't care, because the device works under
Windows, and that is all they support. So getting the firmware fixed is
not an option.
The Linux kernel guys do not want to put work arounds for buggy hardware
(just about every Huawei device type has broken the cdrom/scsi protocol
in some obscure, but different way) into generic code. They recommend
that seeing as the bug is triggered from userspace, it must be fixed in
userspace.
With HAL, it was a simple one-line fix, and the device was ignored by
all applications, and everything worked perfectly. Doing the same in
udev is proving very tricky.
If you can please advise on how to block this in udev, or the correct
place to add the fix in the userland apps/scripts, I would appreciate it.
Thanks,
Justin
