No kidding. Okay, it is also now failing for me with 2.6.16.18. BUT.. with exactly that same binary kernel, it worked fine not long ago --> but I've swapped out userland since then, upgrading from Breezy to Dapper. So something userland in Dapper is triggering this failure, in a way that Breezy never did before. This device has been quite usable until now (the upgrade to Dapper). > Known issue for years.

I have a pl2303 standalone that works fine, but the one integrated into the 1.1 hub/dock is the one that fails. If I plug the 1.1 hub/dock into another external hub, no problems. > Also, look in the -mm tree, there is a fix for this direct error, and > hopefully some ehci fixes that enable the whole thing to work properly. Okay, I'll hunt for that. Do you know of the exact patch? Thanks
