[DIGImend-users] Waltop Sirius Battery Free Tablet 4000 LPI mode

[<yus...@ya...>]

Hi,

I have Waltop Sirius Battery Free Tablet (172F:0502).

I want to use this tablet with 4000 LPI.
(Currently, kernel driver supports only 2000 LPI.)

According to http://sourceforge.net/apps/mediawiki/digimend/index.php?title=Waltop_Sirius_Battery_Free_Tablet,

> As probably all the other Waltop tablets, this tablet has other modes than the default. 
> One such mode is enabled by sending 0x10, 0x01 as feature report with ID 0x02.
> After that, the tablet starts reporting pen coordinates in full resolution of 4000 LPI and all the frame button pressures.

I would like to try 4000 LPI mode experimentally by using libusb-1.0.

To send feature report, I'm not sure which function should I use, libusb_control_transfer() or libusb_bulk_transfer() or libusb_interrupt_transfer()?

If I should use libusb_control_transfer(), what kind of value should I set to bmRequestType and bRequest argument?

Please help me.
