I used to have the same problem with Electrum and my KeepKey wallet.  I fixed it by downloading the python tools for Keepkey.

There are Ledger official python tools available also, have you tried to install them from the command prompt on Windows ?   

Open a CMD window by searching for CMD on the search bar, then, at the command line, type:

I was also intrigued by this posting.  I'm on a Mac, and I connected one of my Keepkey (updated to Bootloader 1.1.0 and FW 6.2.2) to Electrum 3.3.8 - same results, Electrum could not find it.

I have a backup KeepKey that is not updated. It is still at Bootloader 1.0.3 and FW 4.0.0.  When I connected it with Electrum 3.3.8 - it WORKED!  Electrum recognized it. Hummm....  Strange.   I decided to update the Bootloader and FW on that backup KeepKey - after the update, it stopped being recognized by Electrum.  Logically, there is a software issue here - but is it Electrum or more particularly the KeepKey plugin used by Electrum?   Most likely the plugin, I figured.

So I executed the following command in a terminal window:  

   which fetched the latest plugin software from KeepKey servers.

Started Electrum again - and magically both my Keepkeys were recognized by Electrum 3.3.8!  

Most likely the compiled package of Electrum on Mac is not using the latest version of the Keepkey plugin.  

Good catch Belisarius!  We need more observant people in this field.  

I learned something today, due to your post (and the help of kiuupichan on Github): namely that Electrum servers check for P2PKH transactions but not (currently) for older P2PK transactions, which were more common in the early days of bitcoin.

There was a project in 2014-2015 named Encompass (https://bitcointalk.org/index.php?topic=1067166.0) which was based on Electrum codebase, and that could handle 5 different coins at the same time (BTC, LTC, DASH, MZC and VIA)  all with the same mnemonic!  Something similar as hardware wallets do.  More coins could be added by a simple addition of a file and repackaging everything - instructions were provided).  It worked pretty well.  It used the same servers as the stand alone Electrum clones for each coins.  

The project was abandoned in 2015 due to lack of interest from the community - but the code is still available on Github:  https://github.com/mazaclub/encompass

Why still on Linux 16.04?

WCG had 25 months to prepare for the EU GDPR and waited at the last moment to write their legal documents. While they lawyers are writting.... the API used by Tony to provide the daily reward, is closed.

Which Free distribution method listed in the OP are you not finding easy to implement?

Final countdown on the latest 1GB WCG Challenge.  To earn a share of the giveaway, you have to be computing for WCG and be an active member of the WCG official team (Byteball. org) - i.e.: submit any WCG results for each of the final days of the Challenge (Thursday, Friday and Saturday).  

In other words, your WCG username has to appear on the daily payout list (http://wcg.report) AND the WCG Team page (Click Here) for the next three days.   The Challenge officially closes on Saturday 23:59:59 UTC.

World Community Grid does not support GPU computing, only CPU.  If you are interested in similar projects as WCG for your GPUs, there are a few projects that does support them:  http://boinc.berkeley.edu/projects.php  

However, if you end goal is to only collect Byteball rewards, you have to use CPU only.

A Slack user is trying to promote the new Byteball WorldCommunityGrid.org (WCG) distribution method (new WCG Bot in the BB wallet).  This morning, he already gave away shares of a 1GB reward to all Byteball users that were active participants in the program last week, and were part of the official WCG Byteball team (Byteball.org).   Those users each ended up with a 25MB reward (~ $6.60) - not bad.  

With the participation of Tonyh, he has announced on Slack today a follow-up giveaway: he is offering shares of another 1GB reward on May 19th.  To be eligible to receive a share of this reward, the participants have, again, to be active within the Byteball WCG distribution, AND be a member of the official Byteball WCG Team.  Apparently, only 40% of the Byteball WCG distribution users are also member of the official WCG Byteball Team.  To increase this ratio to more than 75% by May 19th, he is offering 1GB in reward.

To be part of this challenge, you first have to be an active member of the Byteball WCG Bot program (tutorial here: https://steemit.com/byteball/@punqtured/processing-for-good-get-rewarded-for-crunching-numbers-to-cure-diseases).

Second, you have to join, or switch to the official Byteball Team (to do so, one has to select "My Team --> Find a Team" in their WCG account, search, select and join the team Byteball.org).

Finally, on May 19th, the Team active members count has to be at least 75% of the number of participants receiving BB daily payouts (https://wcg.report).

It is also mentioned that to be considered an active team member, you have to contribute any amounts of WCG points to the team every day of the challenge period - either since newly joining the Byteball WCG Bot program, or, for current Byteball WCG Bot participants, since the participant switched/joined the official team.

Show me some 2018 data please...

BTW:  your i7 CPU is worth about $300 - not the CPU that an honest user would like to put in jeopardy by stress testing it for a year....

Yes. If you want to be rewarded with the new WCG Points (Honor coin) and the $1 per 150k points.

You have to re-link your Byteball wallet.

All the test I recently conducted, and the results from other users show that a good quad core produces about 15k points per day, and height cores about 25-30k points.

Show us your recent results if you can do better! 

The system takes into account WCG points,  not BOINC points. 

150 000 WCG points = $1 worth of Byteballs

At the current rate of $257 per GB, 1GB = 38 Millions WCG points.

If your PC quad core can generate 15 000 WCG points per day, it should take you 2500 days - or 7 years to produce 1GB   (assuming the price per GB remains the same)

This program is more like a faucet then anything else...

Once your PC is setup - join the "Byteball.org" team within your WCG account.

...except the fact that the xcodeproject file has not been made available on Github since 1.10... you can’t really use that system to generate the latest iOS app for your iphone :/

Yep.

Backups will restore all your Byteballs AND tokens on the networks - like BlackBytes and ICO tokens.  

Seed will only restore your Byteballs.

However, don't operate two wallets with the same backup on two different computers at the same time.  Only one computer at a time should have your Byteball wallet.  If you transfer your wallet to another computer (with the backup) - stop using the previous wallet.
