For three years I have been using an  HP 8300 SFF  in the lab to play with BBRF013, RX888 etc. I have made many modifications to the PC. I added a second USB3.0 controller and about two weeks ago I replaced the system disk with an NVME disk. Almost every day I use BBRF103 or RX888. Suddenly yesterday I cannot connect BBRF103 to the original USB3.0 ports on the back of the PC. When I launch the application the message appears : Fortunately, I have two USB3.0 controllers installed . After trying to change cables and BBRF103 I noticed that everything worked consistently if I connected to the ports of the second USB3.0 controller. I tried resetting and switching off/on the PC several times without any success. The solution was:  - backup and make a restore point - in device management disable and uninstall the affected USB controller - shut down the PC - upon restarting the controller was detected and the driver reinstalled automatically and voila now it works again. The PC is using Win10

I installed a new NVMe disk to the  HP 8300 SFF Thanks to Paulie for this post https://www.tachytelic.net/2022/01/hp-compaq-8300-nvme/  My comparison between the SSD disk and the NVMe disk. The gain in access speed is remarkable. I followed the directions in Ivan's comment to Paulie's post to program the bios flash without a hardware programmer. Hereafter the path I followed: 1 backup your data because by continuing you risk losing it 2 f ormat a USB pen with SystemRescue https://www.system-rescue.org/Installing-SystemRescue-on-a-USB-memory-stick/ 3 install the internal jumper to enable the flash access  see  https://www.tachytelic.net/wp-content/uploads/HP-8300-FDO-Flash-Descriptor-Override.jpg 4 b oot from the pen and select SystemRescue to be fully loaded into ram memory. This allows the USB pen to be mounted and used to exchange the files.bin with Windows 5  run:  # flashrom -p internal -c MT25QL128 -r backup.bin 6 find the USBpen dev name with #fdisk -l    my was sdb1 7 m
