DDJ Ergo - V problem with control

hi

i have exactly the same problem with my DDJ ERGO K (same as ergo v but colour changing and some shape changing)

my config is:

-traktor pro v2.1.1

-portable notebook pc : hp compaq presario CQ60 115ef

2GHZ dual processor ("intel pentium dual cpu T3200 2GHz")

4Gb of RAM

OS: windows vista basic family edition (i don't know how to say it in english maybe it's "home edition") Service Pack2 (32bits)

i use my pc only for that...so i don't understand

please help us

thank you in advance

re hi 

i must add that i have improved my asio from something like 3ms to 29ms to make an attempt to make it don't block

but it's the result is same, (and i don't want to put the asio buffer more than 29 ms because it will be unplayable in casi realtime for the mix)...

Same problem here... Settings of all Usb ports are oke, still doesn't work..

Same problem,,, red light blinking at volume, unit is not recognized on pc\Mac...

What is the solution plss???????

Flashing light on the left volume pad
