Hardware: simple utility for send hex commands to usb device

[Simey]

Hey, a DFP owner here, resurrecting this thread.
First, I want to express my gratitude to all who have contributed, there has been some awesome work achieved.

To start with, I had the same problem as eXSs. USBtool was a no go.
G25manage on the other hand would run fine, except it didn't actually do anything (Because I have a DFP?).

After a bit of hacking of USBtool, and looking at how G25manage does it, I changed this line (line 273) of code in usb.py
From:

Code:

res=usb.usb_bulk_write(self.iface.device.handle, self.addrout, data[:min(len(data), self.outsize)], timeout)

to:

Code:

res=usb.usb_bulk_write(self.iface.device.handle, self.addrout, data, min(len(data), self.outsize), timeout)

This allowed the program to run, and with the aid of running

Code:

sudo rmmod joydev && sudo rmmod usbhid && sudo modprobe usbhid

USBtool told me I had successfully changed my wheel to pro mode.

Here's where I get stuck. USBtool will allow me to change the left and right suck/push values for the feedback, as per the in-built commands, so I assume the program is working now. However, attempting to change the wheel to 900 degree mode results in absolutely nothing happening, those little stops just won't get out of the way.

Does anyone who actually knows what they're doing, unlike me, have any comments about what I might be doing right or wrong?

Edit: The tweak I made to USBtool is of absolutely no use unless you are experiencing the problem outlined in eSXs's post, if you don't have this specific problem, don't bother.
