Yes. So far I've seen these errors only when tablet couldn't give enough power. Such device then didn't have enough juice to power itself on fully and communicate over USB. Powered hub fixed the problem. I've seen this with 2.5" hard drive in usb box, SDHC card reader and XBOX gamepad. Powered hub always fixed the problem, same hub with power disconnected had same problem.

When detected on linux PC check MaxPower parameter of your device in dmesg log. This tells how much power device needs.
