Last week I was setting up my novation dicers and the slave unit has stopped working. I’ve done it all (I think) uninstall and reinstall the driver, powered and unpowered usb hubs, powering the slave with a power pack for cellphones and nothing seems to work, they do however work independently when plugged in as the master but as soon as I try to connect both the slave doesn’t light up at all. Any suggestions or workaround are greatly appreciated.
