When the USB multi card reader is connected for the first time, it works
as expected and four generic SCSI devices are created and mapped to SCSI
disk devices (/dev/sg[2345] to /dev/sd[abcd]).
But each time the multi card reader is disconnected and reconnected four
additional generic SCSCI devies are created and mapped to SCSI disk devices
(/dev/sg[6789] to /dev/sd[efgh] and so on).
Kernel processes are also left when the USB card reader is disconnected:
1097 ? S 0:00 [usb-storage-1]
1098 ? S 0:00 [scsi_eh_2]
1339 ? S 0:00 [usb-storage-2]
1340 ? S 0:00 [scsi_eh_3]
1400 ? S 0:00 [usb-storage-3]
1401 ? S 0:00 [scsi_eh_4]
1577 ? S 0:00 [usb-storage-4]
1578 ? S 0:00 [scsi_eh_5]
A disconnect event is generated correctly when the reader is
disconnected:
May 20 15:16:40 Clever kernel: usb.c: USB disconnect on device 00:07.2-2
address 9
When no more generic SCSI devices are available, the USB reader becomes
unusable and the system has to be rebooted:
