Public bug reported: Ubuntu release Description: Ubuntu 20.04 LTS Release: 20.04
Version package linux-raspi: Installed: 5.4.0.1008.8 Candidate: 5.4.0.1008.8 Version table: *** 5.4.0.1008.8 500 A Drobo unit is an external Raid. My precise model is the 5D3, that can be connected via USB. A Mac computer will see it as an SCSI external hard disk drive of 70TB capacity. Kernel used by Ubuntu 18, would allow to plug in the unit and mount the device. I'm using now Ubuntu 20.04 LTS with kernel 5.4.0-1008-raspi but it doesn't work anymore. The moment the device is plugged in, it is correctly detected: [ 85.177095] usb 1-1.1: new high-speed USB device number 3 using xhci_hcd But some seconds later, there is a firmware transaction timeout and as result, all USB ports are deactivated until reboot: [ 92.733076] Firmware transaction timeout [ 92.733495] hwmon hwmon0: Failed to get throttled (-110) [ 95.356138] xhci_hcd 0000:01:00.0: xHCI host controller not responding, assume dead Because USB ports are now deactivated, it is not possible to assign an address to this new device and therefore it cannot be mounted.
