I hope someone has an answer to these questions:

Currently I run 14 KLN units. There seems to be 2 issues that I run into.

First is the KLN: went idle before work was sent error:

As far as the resources on the Klondike page http://projectklondike.org/, the reason is known, however, as I run a windows 8 environment there isn't really an easy way for me to recompile the drivers. Is there any other solutions to reduce these errors? Future cgminer updates will address this?


The next issue that I seem to keep running into is stability/performance of the units:

Unless I power up the units a certain way, I tend to get a lot of zombie KLN units, or units that are plugged in, however, does not hash at all (zero hash rate, zero work units). Upon system startup and powering of the KLN units, usually all units hash. Eventually one or couple of units will stop hashing at all after a certain period of time (the unit that goes idle is random, physically speaking). As I have 14 units, cgminer should show the units as KLN0-KLN13. The units that go bad will eventually keep trying to redetect itself, and the ID of the unit will keep climbing in cgminer (eg: from KLN13 to KLN253).

Is it possible that this issue be a possibility of USB overload? I have 3 units connected to USB ports in the back pane, 5 units connected to one USB hub, and 6 units connected to another USB hub. Temperatures are under 50c

Thanks for any assistance or knowledge on these matters

-Tried cgminers different versions 3.50+ to latest, no success.
-Only 1 miner was not hashing in the above USB configurations. Plug only 5 USBs in each of the 2 hubs; remainder plugged into the back pane of computer. Currently everything hashes, except two units are hashing at half the rate expected. Using cgminer 3.70.
-1 of the half rate hashers completely stopped hashing after 30 mins.
