CTF840-C Touch screen, USB Unknown
By: wasteme Rank: Starfleet Ensign Postings: 1 From: n/a	Posted: Di Okt 09, 2007 - 08:37 Small problem, installed new screen (CTF840-C) and it works a treat on my home PC, however when it is installed on to my lap top windows reports the USB as unknown. Laptop is : Toshiba Satellite P10-804 OS: XP Home with SP2 USB: 2.0 All current up dates are installed and i have tried the sugestions in the forums and FAQ about screen resulotions ect. Any ideas anyone?

Because of the USB hub the CTF840-C can pull up to 500mA (which meets the official USB standard), however some laptops do not comply fully to the standard. Using an adapter like that might help : http://www.cartft.com/catalog/il/37
