I am copying files to many USB memory sticks. After two drives (/dev/sdc1 and ...sdd1), no device is allocated. I tried from sda..sdm.
There is only one drive in at one time. I keep swapping and writing to the next. Only a reboot will allocate new devices, but with many devices to copy this is taking ages.

usbview does see the next device. Any ideas what to do?

Thanks,
