Dear All,
I would like to ask you for some help regarding placement of a
touchscreen driver.
The device has two interfaces -> I2C and USB.
I2C is well supported and used:
https://searchcode.com/codesearch/view/16778586/
On my board the USB is used (1.1).
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 0
bAlternateSetting 0
bNumEndpoints 1
bInterfaceClass 3 Human Interface Device
bInterfaceSubClass 0
bInterfaceProtocol 2 Mouse
iInterface 0
It shows up as a mice.
And now I'm puzzled, because there are two places where this driver
could be placed:
1. drivers/input/touchscreen/ (and write the driver in a similar way to
usbtouchscreen.c)
2. drivers/input/mouse/ (and for example appletouch.c)
Another question is if this USB interface really is a mouse - I
personally doubt, since for me it looks like USB being only the "other"
transport layer, which "emulates" I2C access to the device
(reading/writing a few bytes).
Thanks in advance for support.
