Re: [PATCH] HID: logitech-hidpp: Enable HID++ for all the Logitech Bluetooth devices

["Peter F. Patel-Schneider" <pfpschneider@xxxxxxxxx>]

Looking at https://bugzilla.kernel.org/show_bug.cgi?id=215699 reminded me of 
another problem with the driver code.   Several HID++ 2.0 features, including 
the HiRes Wheel, have commands with bit fields in them and set all the bits in 
the bit field at once. But when the driver code sets the high-resolution bit 
for this feature it also sets two other bits, ignoring their current setting.  
This prevents other software from reliably using these two other bits, one of 
which is for reporting wheel movement in the opposite direction, a. k. a. 
natural scrolling.

It would be useful for the driver code to first get the other bits and set 
them to their retrieved values.
