I ran this command : # udevtrigger --verbose --subsystem-match=block --attr-match=removable=1
Output was: /block/fd0 /block/hdc /block/hdd These are my floppy drive and my CD and DVD drives. To check if I have and /dev/sd* devices I ran ls -l /dev |grep "sd" which I presume would do it - it produced no output I also just looked at the output of ls -l /dev which had no sd* devices but it did have some usb entries (not sure if this is of relevance?) orac:/# ls -l /dev |grep "usb" crw-rw---- 1 root root 442, 0 2008-11-14 17:45 usbdev1.1_ep00 crw-rw---- 1 root root 442, 0 2008-11-14 17:45 usbdev1.1_ep81 crw-rw---- 1 root root 442, 2048 2008-11-14 17:45 usbdev2.1_ep00 crw-rw---- 1 root root 442, 2048 2008-11-14 17:45 usbdev2.1_ep81 crw-rw---- 1 root root 442, 4096 2008-11-14 17:45 usbdev3.1_ep00 crw-rw---- 1 root root 442, 4096 2008-11-14 17:45 usbdev3.1_ep81 crw-rw---- 1 root root 442, 6144 2008-11-14 17:45 usbdev4.1_ep00 crw-rw---- 1 root root 442, 6144 2008-11-14 17:45 usbdev4.1_ep81 crw-rw---- 1 root root 442, 8192 2008-11-14 17:45 usbdev5.1_ep00 crw-rw---- 1 root root 442, 8192 2008-11-14 17:45 usbdev5.1_ep81 orac:/# I then decided to plug in another USB stick in another USB slot and reran these commands, in case this tells you something. orac:/# ls -l /dev |grep "sd" brw-rw---- 1 root floppy 8, 0 2008-11-14 18:37 sda brw-rw---- 1 root floppy 8, 1 2008-11-14 18:37 sda1 orac:/# ls -l /dev |grep "usb" crw-rw---- 1 root root 442, 0 2008-11-14 17:45 usbdev1.1_ep00 crw-rw---- 1 root root 442, 0 2008-11-14 17:45 usbdev1.1_ep81 crw-rw---- 1 root root 442, 2048 2008-11-14 17:45 usbdev2.1_ep00 crw-rw---- 1 root root 442, 2048 2008-11-14 17:45 usbdev2.1_ep81 crw-rw---- 1 root root 442, 4096 2008-11-14 17:45 usbdev3.1_ep00 crw-rw---- 1 root root 442, 4096 2008-11-14 17:45 usbdev3.1_ep81 crw-rw---- 1 root root 442, 6144 2008-11-14 17:45 usbdev4.1_ep00 crw-rw---- 1 root root 442, 6144 2008-11-14 17:45 usbdev4.1_ep81 crw-rw---- 1 root root 442, 8192 2008-11-14 17:45 usbdev5.1_ep00 crw-rw---- 1 root root 442, 8192 2008-11-14 17:45 usbdev5.1_ep81 crw-rw---- 1 root root 442, 8223 2008-11-14 18:37 usbdev5.32_ep00 crw-rw---- 1 root root 442, 8223 2008-11-14 18:37 usbdev5.32_ep02 crw-rw---- 1 root root 442, 8223 2008-11-14 18:37 usbdev5.32_ep81 orac:/# umounting this second stick produced the original output Russell (still haven't found the way to reply to your post via Thunderbird so I have emailed to the list - I'll post separately on this issue)
