HI just don't want you to waste money sending me another VPforce controller if the problem is to do with AMD's chipset.
WBut I'm interested in narrowing it down, whether the issue is some specific MCU + AMD combination
HI'm not familiar with the specific MCU on my VPforce controller board. Do you happen to know if this MCU has a register setting to increase the differential driving strength (usually in the form of increasing current)? Sometimes driving hard can increase signal to interference/noise ratio. If there is, you can build a custom firmware for me to test out for the sake of curiosity.
Deven if the setting for driving strength is turned off completely, the crash still occurs
DI'm not sold on that it's an issue with the forces applied
Si'm getting this error too, i saw above maybe the
report_id is incorrect? what should it be? Asking because i also have a X570 and every FFB program i am trying crashes in some way.
Wtry report_id=106
Wuhh this sucks
Wneed to find a workaround
Ssame deal
Sis a PCI USB card in my future? 
Slet me try restarting.. it may be stuck from a crashed airforce player
Syep. 106 is firing away
Soh wait it stopped
Wweird that it's 0ms
Wit should run at ~1 ms
Smost of them were
Wdoes the USB reconnect or drop out?
Sno, theres no usb disconnect sound or anything. your configurator still talks to it fine. but can't run hidtest anymore, instant error.
Whmm, maybe the endpoint is in NAKed state... for some reason
Sgotta run for a little bit, have a meeting to connect to
Wroger that, perhaps if you have time we could make a remote desktop session, could try a few things
HWith Wireshark capture, I found that the problem was that the ACK from Endpoint responding to Host's Interrupt OUT got stuck in Host's buffer inside AMD's USB controller. This ACK was never subsequently properly processed and fed back to the host program in the PC. For programs like DCS, it does not allow for any non response from Endpoint, therefore USB hangs causing DCS itself to freeze until USB gets reset. VPforce configurator, on the other hand, doesn't seem to care whether it gets ACK or not so it continues to chug along. The fact that the ACK finally showed up after either we unplugged the USB cable or Walmis' hidtest program cleared itself after HIDException means that the ACK was properly sent by Endpoint (VPforce controller) but, for some reason, was never processed by the USB Host controller inside AMD's chipset.
WI think I might be able to workaround this, @smitty981 ran some tests using a test firmware, and I found out the HID OUT endpoint gets stuck in NAK mode, so I will try to reset it back to active mode
HGood eyes! I didn't bother to look at the content in the ACK sent by Endpoint. The bad ACK has "IRP USBD_STATUS: USBD_STATUS_CANCELED (0xc0010000)" instead of "IRP USBD_STATUS: USBD_STATUS_SUCCESS (0x00000000)". This changes the whole dynamic. I wonder if it's possible to increase the driving strength of AMD's host USB differential driver...
WI doubt that the signalling causes this, it's running at 12mbits, I have 33ohm series resistors on the board, so should be nice and clean
HThen I have trouble understanding why there's never an USB issue when the 20V supply is shut off...
Whmm, perhaps because there's no motor communication = less interrupt load
Wmight be some race condition, that's amplified with AMD board 
Wahh, the wonderful world of embedded systems
Sha, my rudder board had motor power and the joystick didnt.. hidtest still running on joystick board no errors
HHaha! I don't envy sitting on a boiling plate... After all, AMD should have done something about it!
Dhow long do I leave the python run for?
D
DI kept it running, loaded into a DCS module viggen, exited the module and the python script stopped working
Dand now the script doesn't want to start
Dwhatever effect 7 is, is the one that hangs the system
Dsurprisingly, I was just in the spitfire and effect 7 was on/off continually, no issues, but as soon as I jumped into a mosquito, it happened pretty quickly
Sis there a way to change the singlemotor kit to the other axis? xpforce seems to want it on X
WYep, I'll get back to you
WI think I will be able to fix this today
Dooh, let me know and I can test
WIt's released 
H@walmis The new FW works for me. DCS does not freeze anymore plugging in my AMD X570 provided USB ports. Now I just need to figure out what to do with this PCIe USB card I bought. Great work!
VKeep it for troubleshooting, they come in use more often than once. unless you splurged on an $80 pcie card
HThat's what I'll do. Thanks!
WAwesome, thanks everyone helping to debug this!
Dit's working, thank you
Poh, sweet, thank you for the fix, @walmis I'm having exact same thing with my x570 and dcs crashing with effect7 (regardless which AC)
R@walmis does it matter what max psu is set to in VPForce? I have a 19.5v 11.8a psu but it doesn't really make a difference if I set it to 11.5a or 8a. In both instances it peaks around 30a on full deflection and settles to around 25a.
