Waking up a USB scanner, other than reboot
Hello All, I have an Agfa SnapScan 1236. If it is not used for a while, it goes to sleep and even turns itself off. I would like to be able to wake it up, without a reboot,without disconnecting power, without disconnecting the USB cable. Does anyone have ideas? Even when it is "misbehaving" running snapscan -L will find it, but using snapscan to actually scan a document fails to open the scanner. Even when used after a boot, I need to scan the first page I put in twice, it is a medical capable scanner with a lamp in the lid as well as underneath. I would like the first scan to not be in transparency mode. I was given it by a medical practice who have migrated from film X-Rays to digital ones. This will also help for when I do want to scan transparencies. Regards, Mark Trickett

Mark if you are not looking for some kind of hardware fix; shouldn't you be specifying distribution, version number, current driver...... etc ? regards Rohan McLeod

What I am more looking for is how to poke a code to the device, to the USB port, and what should the code be. Someone may be able to suggest something. Snapscan supports device specific commands. What searching I have done on the net reveals I do not know the right search terms. What I am looking for is both hardware (specific) and software (generic). Regards, Mark Trickett
