Use the supplied USB cable and the tablet is powered by AC. USB power is often reduced on battery power so you will see this issue. Be sure to test the drive on other PCs. If it works on other PCs you ask Acer why it didn't work.
I am trying to install a Samsung SE-208 optical drive on to an Acer Eee PC Seashell Series tablet running Win7 Startup.
The drive is powering up on the USB connection but does not show up with an assigned drive letter in Windows Explorer or My Computer.
It does show up in Device Manager in Control Panel as a working unit i.e. without the yellow triangle denoting an unrecognised item. Any attempt to update the driver results in a messgage confirming that the current installed driver is up to date.
Any suggestions would be appreciated.
