I just did my update to H90Control 1.8.16 and it was able to install the 1.9.11 firmware, however, now when I boot the H90 and attempt to connect I get “Error communication with H90 ‘XC-99999’ device may not be ready” Anyone else experiencing this? I’ve try two different USB cables that work with other USB pedals, but not the H90. Is this a common issue that is need of a bug fix?
Are you using a Windows machine? This may be related to an antivirus software issue. You can try disabling the SafeCam setting in Norton antivirus if you are running that software.
