I'm sorry for the delay in replying, yes this is still an issue.

On 5.4-PRERELEASE Sat Mar 12 10:56:24, I get the following:

umass0: Hewlett Packard HP USB CD-Writer Plus, rev 1.00/0.01, addr 2
umass0: CBI reset failed, TIMEOUT
umass0: CBI reset failed, TIMEOUT
umass0: CBI reset failed, TIMEOUT
umass0: CBI reset failed, TIMEOUT
umass0: CBI reset failed, TIMEOUT
umass0: at uhub2 port 1 (addr 2) disconnected
umass0: detached

(Note that each timeout message is two minutes apart, so the above process
takes 12 minutes).

On 6.0-CURRENT I suspect I'd have got the same if I'd have left the drive
in long enough, but instead, being impatient, I removed it after about 60
seconds and recieved a panic in camisr().

umass0: vendor 0x03f0 HP USB CD-Writer Plus, rev 1.00/0.01, addr 2
umass0: at uhub0 port 2 (addr 2) disconnected

I'm happy to test anything you want me to try, but as this isn't my CD
writer, it may take a while...

Thanks
