Public bug reported:
Hi!
PC: Toshiba Satellite p205 laptop
Enclosure: Acomdata Samba USB SATA/PATA enclosure with Hitachi SATA2 500GB
drive.
Ubuntu: Hardy
Kernel: 2.6.24-16-generic, 2.6.24-19-generic
When hot-plugged in the enclosure is not detected. No /dev/* device created.
Dmesg shows errors.
When cold-plugged (before boot) it is detected as /dev/sdb.
'sudo modprobe -r ehci_hcd' allows to hot-plug the enclosure once and works at
~1mb/s speed (USB 1.0?)
'lsusb' does not always list the device (it may appear on one call and
disappear on subsequent calls)
However, hot-plugging the same enclosure to my Ubuntu Hardy desktop works as
expected 100%.
Thank you.
'lsusb'
