February 4, 20215 yr Last week I picked up used server with an ASRock Rack D1541D4U-2T8R motherboard, created a USB boot drive (Samsung MUF-32AB/AM FIT Plus 32GB), plugged it into the USB port on the motherboard, everything worked as expected. I was able to access unRAID from my browser and had no problems with it running, so I shut it down till I could get it racked. Fast forward to last night and now it will not boot. It starts to boot unRAID OS, but gets hung around the following line (screenshot attached below) ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver. I've since tried the following but all have the same outcome: Copied USB drive contents to a different USB drive (Kingston DTSE9 32GB) Created a new USB boot drive on the Kingston USB Created a new USB boot drive on the Samsung USB Tried booting each of the USB sticks in different ports (all are USB 3.0) Any suggestions or ideas as to what is going on here and what I need to change to get this to boot?
February 4, 20215 yr Community Expert Are you actually getting an Unraid boot menu on the console? Is the flash drive plugged into a USB2 port?
February 4, 20215 yr Author Yes. I've tried booting into Unraid's safe mode as well, but to no avail. The motherboard does not have any USB 2.0 ports, only USB 3.0.
