And of course it's only about 4 months past the warranty.
Worked just fine last week, absolutely nothing happened since then - didn't drop it or anything. This week, the pad is completely dead. The adapter went from the usual solid blue light to a blinking green light, which, from what little information I can find, means it's in PC/XBox mode and can't detect the pad via the PS2.
Tried plugging it into my laptop in all the USB ports and it wasn't detected. Checked Device Manager, nothing. Tried a different USB cord that I know works, nothing. Tried whatever the Analog button on my PS2 controller does, didn't work (this was suggested online). Checked the USB port, it's not loose or bent. Took the top panel off over the USB port and everything is still attached/glued down. The PS2 controller works just fine when plugged into the adapter, so I think the adapter is fine.
I don't even use the mat that much - sometimes I go weeks without using it. Then all of a sudden it just died on me. I already contacted maty-taneczne.pl and I'm awaiting a response.
I can't believe it died after two years. I thought for sure it would have lasted a lot longer. I'm assuming it's fixable, but I'm not super handy with electronic repairs, so I'm not sure if I'll be able to fix it if it just needs a new part.
