For some reason I have to reboot to recognise USB storage devices. I thought it was the hotplugger that wasn't working, but see this output from dmesg on insertion of the LACIE external 20gb:

Code:

hub.c: new USB device 00:1d.1-1, assigned address 2
scsi1 : SCSI emulation for USB Mass Storage devices
usb_control/bulk_msg: timeout


usb-utils shows it too:

Code:

[root@LUCI DOWNLOAD]# lsusb
Bus 004 Device 001: ID 0000:0000 Virtual Hub
Bus 003 Device 001: ID 0000:0000 Virtual Hub
Bus 003 Device 002: ID 059f:a601 LaCie HardDrive
Bus 002 Device 001: ID 0000:0000 Virtual Hub
Bus 001 Device 001: ID 0000:0000 Virtual Hub


However cdrecord wont pick it up, and of course I cant mount it or fdisk /dev/sda/b/c/d it.

Code:

[root@LUCI DOWNLOAD]# cdrecord --scanbus

[root@LUCI root]# fdisk /dev/sda
 
Unable to open /dev/sda


I have tried
Code:

rmmod usb-uhci
insmod usb-uhci
(and it sometimes hangs)


Any ideas how to mount my USB devices without rebooting?

It dont even work on reboot. I found this article:

But same thing applies, USB storage devices still require a reboot *some* of the time. Does anyone else experience this? (9002)

I've noticed that USB is quite a bit nicer in 10000. Basically, you can use the Menu->System Tools->Disk Management program to mount/umount USB devices. I've only used it with one device at a friends, but it worked really well. A "regular" user can mount/umount all from a gui. It puts a link to the device on the desktop when the device is mounted. Requires no command line.
