I recently purchased an ASUS Q550LF laptop with Windows 8.1 preinstalled, and subsequently installed Ubuntu 14.04 and Debian 7.6. I use Ubuntu for most tasks, but occasionally have reason to boot Debian. The problem is that Debian won't boot. At some point during the boot process, I receive variations on the following error messages:

[time] usb 1-7: unable to read config index 0 descriptor/start: -71
[time] usb 1-7: can't read configurations, error -71

[time] usb 1-7: unable to read config index 0 descriptor/start: -110
[time] usb 1-7: can't read configurations, error -110

They repeat indefinitely, and the boot process hangs. I don't have a problem with the touchscreen in Windows or Ubuntu, so I suspect some problem with Debian. When booting Ubuntu the same error message occurs, but eventually the touchscreen is recognized:

I can't disable the touchscreen in the BIOS, and most of the purported solutions I've encountered when researching the problem don't work. I'm not even sure how I would go about solving the problem. If someone could point me in the right direction, I would appreciate it. Thanks in advance!

Does every USB device have enough power to do what ever it wants when everything is connected? Does it work if you disconnect all other USB devices?
