I recently purchased an Analog Discovery 1 Rev C unit and am having problems getting Waveforms 2015 to open the device. I have read the troubleshooting guide and the posts here with great attention to detail. The device shows up in Device Manager correctly as a FTDI unit and passes all the Windows tests. Running Win7 Pro in 64 bit mode. Waveforms recognizes the device as "Discovery"in Device Manager and shows the correct serial number, though it adds "210244" in front of the number on the unit. When I select the device in Device Manager the Opening Device dialog box appears, but I get the Device Opening Failed dialog box with the message-
"DptiIO failed ERC: 0x7"
"Device configuration failed (PLL3)." The Red LED inside the case near the USB port always flashes briefly during each opening attempt.
I get this across 2 different computers, both Win7PRO-64. I have tried EVERY combination of 3 different USB cables (one only 12" long, both direct to every USB port front & back, and through 2 different powered USB hubs. I get this EXACT situation 100% of the time, on at least 50 tries. If nothing I am through I cannot get far enough in Waveforms to check the device current specs. I have attached a screen dump of the error message if that helps.
Just for the heck of it I installed Waveforms 2 on a third Win7-64 machine and got the same results.
Reading through the support post here I see some users have had to re-flash firmware and/or EEPROM/FPGAs. I have not made any attempt to rename or calibrate the unit.
