I have found that there may be an issue with ubuntu 10.10 and this tablet. For me, it seems that the MTP crud is interfering with adb. If I freeze the MTP application on the tablet, I have no problem.
...and now it gets even stranger: If I boot ubuntu 10.10 in a virtual machine (vmware 8.x), its fine even with mtp enabled.
I haven't had any issue at all with my gentoo boot. (However, I've been trying to do the android development with ubuntu as it appears to be directly supported by google.)
(This really isn't an issue for me, as I actually prefer to keep MTP disabled so I don't get popups.)
