UHCI error when connecting Wacom tablet.

I have this wacom tablet, identified as a Wacom MTE-450 (Bamboo). When I connet it to Haiku it seems thst it would almost work but then a UHCI error happens. Here is what I see on syslog:

KERN: usb hub 2: KERN: port 0: new device connected
KERN: wacom: add_device() - wacom detected
KERN: wacom:  ... success!
KERN: usb error uhci 0: td (0x037c0d20) error: status: 0x004407ff; token: 0x00e0042d;
KERN: wacom: add_device() - control transfer 2 failed: -2147483639
KERN: void AddOnManager::MessageReceived(BMessage *) what: NMP_
KERN: wacom: device_open() open: 2

After this, the tablet does not work.

The device does either not respond or doesn't handle the request and stalls it to indicate that. Since the error counter counted down to zero though it looks more like an actual device timeout. Anyway assigning to Stephan as it's his driver.

I think this is the same bug as described in ticket:3744. In both tickets control transfer 2 fails.

The Linux driver tries control transfer 2 five times before giving up, because some tablets don't pick it up the first time.
