Problem with a Happ 3" USB Trackball!
Raider:
Thanks guys!
Connections look good on the trackball unit. I can't spot and bends or frays, loose or exposed wires/connections, etc.
No I am not using a self powered hub. Did consider it though, one that's self powered. I checked my usb bandwidth consumption and it's zapping about 23%. More than twice my other little Logitech trackball mouse... And yes I did remove the Logitech software. So your right, definitely a hungry little device! Also I did try hooking it up as the only USB device. Same prob!
But I may have sorted the prob! What I have done since last checking here is to disable the "error detection" on my usb host controllers from the device manager. So far I've had my box running just over half a day now since doing that, and the Happs trackball has been stable. So it's looking like that might've fixed the issue. :)
If not, I will definitely give the "Self Powered
hub a try!
BTW urrebelscum! Good damn work with your MAMEanalog+! I love it!

Glad to hear it's working. :)
Hmm, the happs USB-PS/2 connector having communication errors could be due to minor power problems, but then again, could be something non-standard about the happs USB chip. *shrug* If you don't mind, could you let us know how it goes in the long term, and anything happs might tell you? Just for my curiousity. ;)

Does anyone know if it's the trackball itself that requires so much power, or their USB interface? I have a standard Happ trackball interfaced with a USB mouse hack; the trackball pulls its power from the USB mouse's board. Am I setting myself up for power problems?

Raider:
The power consumption on mine is 100mA on a 500mA max port.
Okay heard back from the HAPP Controls people. After going through a checklist, the tech concluded that it's probably enumerating again and again and that it's most likely got a fault in the trackball. SO back in for warranty replacement!
Kinda sucks I'll have to wait a couple weeks to get a trackball going again. But at least they are standing by their product!
