dmc_tsc10_init() returns -ENODEV (-19) when device responds with
something other than 0x06 0x00 to the "reset" and "set rate" commands.
It would be interesting to see what your touchscreen responses are.

Yes, thank you!
I just had a look into the datasheet.
(tsc10usb_pi_e.pdf, Rev. 1.2 from November 1, 2005)
and I will need more debugging info to the dmc_tsc10_init()...

As I wrote, I am using the TSC-103 without EEPROM.
(I can add one if it's of any use.)
The PanelID is 0 (pin 3 [SEL1] is low), so it's the "first"
device on the bus.

What exact chip version and EEPROM configuration do you use?
I guess there are different firmware releases for the different
TSC-10* devices which behave... well... different. :-(
