Hi, i have some good news, i manage to flash back the original 2mb pch bios and the invalid device descriptor is gone from the device manager my only problem now is the graphic card the nvidia always appears with code 43, i have install the latest driver from nvidia site but no luck. My question is, will the main bios has anything to do with this problem on the graphic card? This graphic card has the optimus tecnology.

try this, flash both chips, remove cmos battery

and of course install all drivers and utilities given by toshiba for this model, and if all works well try then to update driver from nvidia

Re: Bios Dump Toshiba L50-A-1CU PSKK6E

Hi, i have flash the two bios and the same problem code 43 on the graphic card and with this bios the usb invalid descriptor appears again.How can i see if the original bios has a error so i can fix it or see it.

Hi, i have manage to flash back the original bios file now i only have code 43 on graphic card, i suspect that the problem relies on the chip of the graphic card. Thanks, all for the help so far.
