Hello, i have an Aquaero 5 pro, and a PowerAdjust 2 Ultra. PC is using Win7 64, 12GB RAM, motherboard is EVGA X58 Classified.
I have Logitech mouse & keyboard, run the "dimr" tool to confirm polling rate is 125Hz, so no problem here.

If i load up the old Aquasuite 4.72 and i plug my Poweradjust 2 on USB, it's working perfectly. I can see the flow monitor properly (which my AE5 cannot, on firmware 1010 - i have one flow sensor plugged on my PA2) and fan rpm monitoring is correct. My PA2 is on firmware 1003 so i uninstalled AS 4.72 and moved on to AS 2012 beta 9. Unplugged the PA2 from USB, plugged the AE5....

Then i launch AS 2012. It sees my AE5, good. If i go to "system" page my AE5 pro shows as "aquaero 5 lt" which it is not, it's a pro version (with the LCD). Firmware is 1010, if i try to flash it holds and doesnt even start flashing at all. Nothing happen on the device either.
Now what do i have to do ? The AE5 still works, if i close and relaunch the aquasuite it still sees the device properly. It just doesnt want to flash, and of course the aquasuite is unusable (sensors names are all crypted, data is wrong). My AE5 is mounted at bottom of a case, i will have to empty water and dismount everything to access it.
I can access the USB data cable easily (it comes out on top of my PC).

(edit) i managed to flash the unit after a long struggle... First try almost bricked the unit for some reason (LCD was only showing left half and data was junk) but another recovery mode trick and it works now.. whew. So only way is to use the jumper trick... AC please for next units, think of a front-panel recovery mode access, like keeping the 3 buttons pressed when powering up the unit for example, or a konami code, whatever...
