having trouble, too
Hi! seeing as this is the only usb-psx thread I could find, I'll post in this one rather than starting a new thread.
I've got a similar problem. Running Mandrake 10.1, with a Super Dual Box (a nice device despite the cheesy name) usb-psx adaptor. On Sunday I was playing a great game of Stepmania, and on Monday it wasn't recognizing any button presses. I've done rather extreme things to see if I could get it working again, including wiping the drive and starting over. But nothing works.
cat dev/js0 and cat dev/input/js0 produce the random character junk they're supposed to when run, but not when I press any buttons. So I know it finds the joystick just fine; it just can't read the input from the joystick.
The joystick appears to be plugged in correctly as well; Windoze reads the input correctly.
What's baffling is that it worked just fine on Sunday and I didn't even restart the computer between then and Monday. EMSUSB has been recommended as an adaptor, but before I buy it (or anything else), is there something else anyone can recommend, please?
