Or, are you overriding the pools difficulty setting?

Bingo!

I doubt your laptop will provide the needed 3.1, or so, Amps.  A powered hub would be better, but most of those don't provide that much current either.  Sidehack makes his own powered hub for this purpose.  Windoze doesn't work well, most people use a Pi 4 and a GekkoScience Hub.

Make sure you have a good fan on it too.

Well, I guess after you try a new USB cable, you need to contact the dealer you bought it from.

Yes, I'm referring to using Zadig to install the WinUSB driver.  So if the device isn't being recognized then you must have bad hardware somewhere, miner, PC, cable, Power Supply, ...

Well, you have to get that done, it's not optional.

Did you install the WinUSB driver?

Still makes no sense resurrecting a decade old thread instead of posting in the proper support thread.

Here's the support thread for the Compac F's:

Also, you should be posting in the actual support thread for this miner instead creating unneeded threads.

Just in case you didn't see it:

Well, in your green circle the 01 means one chip and the + means it's using ASIC Boost.

Most of this is explained in this thread and/or in Kano's support page.

I'm definitely not suggesting running it off of the USP port of a RPI.

I just meant any USB Powered Hub should be sufficient for a USB Block Erupter.  I used to run 4 of them and an Artic Breeze fan per 5 Port Rosewill hub which has a 2.5 amp Power Supply, if I remember correctly.

Dave,
He is using 1, original, Block Erupter.  It only consumes 2.5 watts of power.  So any USB hub can power this and an Artic Breeze Fan.

Your miner is working fine.  It is hashing at 335Mhash, which is correct for that miner.  That pool is showing it offline because your miner hasn't found a share meeting the pool's minimum difficulty, yet, and that is because your miner is only hashing at 335Mhash's, that is old GPU speed.

It isn't broke so don't fix it.  You have accomplished your mission.  Your old miner is mining.

It is not finding blocks, only reporting that blocks are being found.

Edit:  You can try mining on Kano.is, it has an 8k minimum difficulty and will adjust down to 442.  Your best share is 128k so that would have submitted a share.  However Kano doesn't allow GPU's so his pool may ban you for being GPU speed.  You can also try solo.ckpool.org it has similar minimum difficulty and adjustments.

Edit2: Looking at your screen shot again, with my glasses, I see that it has submitted a share and the pool is showing you an estimated hash rate based on that one share submission.  So the pool says it is working as well.  So don't get wrapped around the axle about the offline thing as that is only because of the slow share submission rate.

Your miner is working so just bask it the warm glow of your success.

It's working fine.  It will take a really  long time to find a share with a high  enough difficulty for the pool  to accept.

Did you look through the CGMiner thread and/or read the readme?

When are you getting stale shares?

If after a block change then it is normal.  Your miner sometimes continues to send shares from the previous block when a there is a block change, until your miner receives new and valid work.

If not, then I don't know.
