I have a Toshiba A65-S126 Celeron 2.8GHz / 512 MB / 60GB / USB2.0 system and a Seagate 160GB USB 2.0 external drive. When I start TI using boot CD or recovery manager, it gives an error similar to "usb device not accepting new address" twice and does not show my ext hdd; rendering TI useless! interestingly, I have a much older Dell Latitude laptop C610 Pentium III 1GHz / 512/ 20 GB / USB1.1 system, and if I connect the Seagate external drive to it, TI recognizes it without any problems! however, I am trying to back up the new system so the fact that it works with the old system is of no help except in hoping that someone here would be able to help figure out whats going on. btw, I tried "acpi=off noapic" and it still did not work. interestingly, if I remove the "quiet" option, it comes to the # prompt and hangs. In my old system, it does not hang and allows me to enter commands. Is the Toshiba system not compatible with TI 8.0. FYI. TI build is 771. Appreciate any help! Thanks.
