I recently purchased a DDRC-88A with the BM plugin from a forum member and managed to run a configuration and was very pleased with the results. Noticed last Friday there was new software/firmware available. Downloaded the files, unzipped the manual, dlct, and the hexfile. Tried to update the firmware from the firmware hexfile and the bridge popped up and said "Device Found. Message from USB followed by a countdown (starting with one), then Byteread = 65" The countdown went over 300,000 bytes (took almost two days) then my PC running Win 10 decided to do something (probably maintenance or security, since turned off) which turned off the "Connected" in the 88 and the countdown started all over again when I reconnected. Obviously I am doing something wrong. Please help. How long should the firmware upgrade take, how many bytes? I had the same problem right after I first tried to set up the unit, before the unified upgrades became available last Friday, I would click on the "upgrade firmware" beneath the "Restore" on the 88 screen and the download would commence, several days (I think 3 days) later I was up to over a million and a half bytes before I inadvertantly touched something on my screen that re-started the countdown. I gave up; however, the previous version, 2.19, apparently remained and allowed me to run a configuration with what I thought were very good results. So, after two hours this afternoon the Bridge , running in the background, says 20,800 and counting fairly rapidly, but I am obviously not doing something right. Suggestions?
