Subject: [2.6.31-rc8] Problem with detect USB devices
Bad version: 2.6.31-rc8
Last known good: 2.6.31-rc7
Observed on two different machines. Upgraded Debian Testing.
udev 0.141-2
hal 0.5.12~git20090406.46dc48-2
usbutils 0.84-1
==============================
Descriptions:
1. When plug usb flash drive and turn on computer, device manager in
KDE4 show it, and I can mount. When remove device very often icon
doesn't dissapear - KDE doesn't refresh informaton about connected
devices. When connect again, I can't mount it.
2. Sometimes when I remove and connect device again, then is listed twice:

http://unixy.pl/maciek/download/kernel/2.6.31-rc8/zlom/snap2.jpg
3. Plug in flash drive (a), then flash drive (b), remove (a or b),
remove (b or a), KDE still shows icons of flash drive (a/b)
4. Similar with USB printer
5. I this cases (1-4) lsusb doesn't show connected devices
6. VirtualBox also has similar problem connect with USB devices.
==============================
For example:
a) Connect flash drive, turn on computer (similar when plug device after boot):
maciek@...m:~/Desktop$ lsusb
[...]
Bus 001 Device 002: ID 3538:0054 Power Quotient International Co., Ltd
Flash Drive (2GB)
[...]
b) Mount:
lshal:
15:12:56.866: volume_uuid_599D_1168 property volume.mount_point = '/media/pqi'
15:12:56.867: volume_uuid_599D_1168 property volume.is_mounted = true
c) Unmount:
lshal:
15:13:46.528: volume_uuid_599D_1168 property volume.mount_point = ''
15:13:46.529: volume_uuid_599D_1168 property volume.is_mounted = false
maciek@...m:~/Desktop$ lsusb
[...]
Bus 001 Device 002: ID 3538:0054 Power Quotient International Co., Ltd
Flash Drive (2GB)
[...]
d) Remove device:
lshal:
<doesn't show anything>
KDE4 device manager still shows icon of flash drive
