* | | Input: wacom - Bamboo One 1024 pressure fixChris Bagwell2012-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bamboo One's with ID of 0x6a and 0x6b were added with correct indication of 1024 pressure levels but the Graphire packet routine was only looking at 9 bits. Increased to 10 bits. This bug caused these devices to roll over to zero pressure at half way mark. The other devices using this routine only support 256 or 512 range and look to fix unused bits at zero.

When a wireless tablet connects, it reports same USB PID used if tablet is connected with USB cable. Use this to update features values, set input capabilities, and then register device. From there, the Pen and Touch interfaces will reuse the existing tablet's IRQ routines. Its possible that 1 receiver is shared with 2 tablets with different PID (small and medium Bamboo for example) so the input is unregister at disconnect to better support this case.

When its receiver is plugged into USB, it presents 3 interfaces: 0) Monitor 1) Pen and 2) Touch. The exact capabilities of the Pen and Touch interfaces can not be determined until a tablet connection is established and reported over the Monitor interface. This patch detects this wireless receiver and enables interrupt packets to be processed for the Monitor interface. Processing the data in packets will be left to another patch. Since it doesn't make sense to create an input device for the Monitor interface, it is not created. Creation of Pen and Touch input device is also delayed until monitor packets can be processed.
