I have a lenovo thinkpad with a firewire express adaptor card that I recently setup for recording. I connect my maudio controller either/and via 5 din midi to my audio interface or via usb to my laptop. At the moment I need to be able to connect via usb midi.
I am using Ubuntu Studio 14.01 LTS with KXstudio repositories. ( I am not writing from my laptop at the moment so I can't recall the exact kernel at the moment), I am getting messages that are close to :
....usb-2/1 device not accepting address 4, error -110 usb 1.0 unable to enumerate usb devices....
I will have to access the logs to get the exact boot errors.
My maudio controller has mostly worked fine and when the usb midi was not recognised I rebooted and switched to a powered usb slot and then it worked. Now it will not be recognised no matter what usb port or whether I still power it with an AC adaptor as well. I even got a single AB usb 2.0 cable thinking it was having a hard time recognising my usb extension cable. I never have had any issues with usb midi on my desktop and Ubuntu Studio.
I was wondering if any ever had such issues and how did they resolve it??
