Binary package hint: linux-image
OS: Ubuntu 9.10 (Karmic Koala)
Kernel: 2.6.31-17-generic
I've got a PowerSync HU-210B USB 2.0 4-Port HUB, which is based on the
Alcor USB Hub chip (058f:6254 Alcor Micro Corp. USB Hub). After
performing Safely Remove Drive on a USB flash drive connected to this
hub, the USB port no longer reacts to plug/unplug events (gets stuck at
"suspend" status), until the hub itself is disconnected and reconnected
to the upstream.
Since the problem is not reproducible in Windows XP, I guess it's caused
by a bug in the linux-usb subsystem.
