I've been experiencing very slow USB transfer rates, ZWO support suggested I reset the firmware. I rolled back to the previous version successfully. But when trying to upgrade the firmware to the latest version, It never completes and I get the message:
File transfer takes too long, try quitting and reopening the app, if this does not resolve the issue, try restarting ASIAIR device.
I've tried doing both several times. I am unable to upgrade to the latest firmware.
