I'm working on a brand new Dell Dimension C521. It only uses USB keyboards & mice. There are no PS/2 ports. This is an AMD dual core machine. I got news about v 10 being released and decided it would be a good time to upgrade. The only way I can get TI 10 to work is to boot in safe mode. This let's me use the keyboard & mouse and still see an external USB hard drive. However it is dog slow. Really slow. 8086 slow. I hesitate to even call it usable in this mode. When I boot into the full version, the error msg appears "usb-ohci.c : USB HC Takeover failed! " at that point the USB ports turn off. *IF* I add "acpi=off noapic" to the linux boot arguments then I retain the keyboard and mouse. However the external hard drive is not mounted. I am finding it hard to believe that these USB issues that have been around since TI 8.0 are still not resolved. This is getting to be onconscienable. Your product is being targetted as to be the best imaging system out there and you're not supporting hardware in a way that matters to customers. I understand you're going to want my dump log (pun intended). I'll trade you for it. Give me and all your customers Acronis products that run on a Linux 2.6 kernel instead of the 2.4 kernel. Trade?
