Hello all.

I've been having some issues with my HD500 recently.  First of all, the block inside the USB socket that holds the pins in place broke off - sent that back to L6 via the retailer to get that fixed, everything was hunky dory, then more recently I've noticed the expression pedal seems to be not working - the toe switch is fine, but the pedal itself doesn't seem to be registering as moving.  I've tried most of the solutions I've seen on here - reflash firmware (which I had to do anyway as I had the 'endless reboot loop' issue - I'm beginning to think this POD is cursed!), global settings reset, calibrated the pedal (which didn't seem to work the way it should - when I got to the stage of pressing the C switch to check the sweep of the pedal, it didn't show any change regardless of where the pedal was, and when I next booted up the POD, the volume pedal values of all the presets were stuck at 0). 

So, I'm beginning to think the pedal itself is non-functional rather than a firmware gremlin of some sort, but I thought I'd check with my fellow HD500 owners - have I missed anything out, or am I going to have to lug this thing back to the shop I bought it from AGAIN?
