Most likely you have to connect the DVD drive via a powered USB hub.

Maximum USB current on RPis is 1.2A - for all 4 ports combined. If you exceed that (eg if the DVD drive or a USB HDD needs more when spinning up) you'll get the symptoms you described (USB reset, devices "falling off the bus").

See also the RPi FAQ FAQs - Raspberry Pi Documentation

From the Raspberry Pi B+ onwards, 1.2A is supplied to downstream USB peripherals. This allows the vast majority of USB devices to be connected directly to these models, assuming the upstream power supply has sufficient available current.

Very high-current devices, or devices which can draw a surge current such as certain modems and USB hard disks, will still require an external powered USB hub.

Just use the latest LE release (9.2.4), it already includes all fixes. I removed the temporary test build from my server a long time ago.

keep GPU mem as it is (76MB) - that's not needed with the new driver and only wastes memory.

Only H264 HW decoder needs GPU mem and 76MB should be plenty for it. New driver needs CMA memory (which we already default to 384MB ATM).

If you updated from an older version please replace your config.txt with the one in /usr/share/bootloader/config.txt - some important settings have changed and the file isn't automatically updated/replaced yet.

as for remote.xml: please provide a kodi debug log.

Are you using Wifi? If yes try a wired connection, badly shielded USB3 devices are known to interfere with 2.4GHz wifi usb3-frequency-interference-papers.pdf

You seem to have linked to the wrong image, for RPi4 you have to use the RPi4 images - eg LibreELEC-RPi4.arm-9.80-nightly-20200924-4722b9e.img.gz

4k support isn't implemented in the driver yet, that's being worked on and will come later when it's finished.

We are currently testing kernel 5.9 with a newer version of the display driver and changed the config a bit so you won't get a black screen with hdmi_enable_4kp60=1 in config.txt. With current nightly test images you could add disable_fw_kms_setup=1 to config.txt to avoid that issue - see linux (RPi): update to 5.9 by HiassofT · Pull Request #4562 · LibreELEC/LibreELEC.tv · GitHub

Not sure about the remote.xml issue, you'll have to post a kodi debug log. ./userdata/... looks wrong though, that should be /storage/.kodi/userdata/...

There are no separate docs for LE, just have a look at the official RPi docs linked here GitHub - raspberrypi/rpi-eeprom: Installation scripts and binaries for the closed sourced Raspberry Pi 4 EEPROMs - there's also a ton of threads about how to use rpi-eeprom-update / rpi-eeprom-config on the RPi forums (or just call these scripts without parameters and you'll get the usage info).

Only difference on LE is that you don't need to run these programs with sudo as you're already logged in as root.

BTW: probably the easiest way to get the latest eeprom / VL805 firmwares is to boot the eeprom recovery image from SD card - this'll give you the Sep 03 bootloader version as well. Either use RPi imager on your PC or the recovery image from here Release rpi-boot-eeprom-recovery-2020-09-03-vl805-000138a1 · raspberrypi/rpi-eeprom · GitHub

Yes, correct.

The eeprom update in LE settings will only update to the latest critical firmware (which doesn't support USB boot, as the version in LE 9.2.5 is now outdated).

The latest stable eeprom firmware (from July) is included in LE 9.2.5, but only for manual update, and is now outdated as well.

Either use RaspiOS or pull the Sep 03 firmware from github rpi-eeprom/firmware/critical at master · raspberrypi/rpi-eeprom · GitHub and do a manual eeprom update in LE.

You have to update the bootloader eeprom to a newer version. Easiest way to do this is to run a current RPiOS (ex Raspbnian) image from SD card, that will auto-update the bootloader to the latest version with USB boot support.

This is the shortened githash of the master branch the build was created from - you can look it up eg with Merge pull request #4556 from CvH/10.0/espeak · LibreELEC/LibreELEC.tv@1fcfe6a · GitHub

GUI tearing on RPi4 is a well known issue. It'll be fixed in LE10 which uses the new kms driver.

Just leave it, it's fine.

We provide stable firmwares just as a convenience for advanced users, if you want to track newer firmware versions that were released after the LE release it's easiest to do that with RaspiOS/Raspbian or download them manually from the rpi-eeprom gitub repo.

If you just ran "rpi-eeprom-update" (without "FIRMWARE_RELEASE_STATUS=stable") then this output is expected.

You previously updated to the stable version (Jul 16 bootloader, 000138a1 VL805) and this is shown as "CURRENT". But rpi-eeprom-updates checks latest in critical (unless you set the release status info) so LATEST shows the available critical versions from the LE image (Apr 16 bootloader, 000137ad VL805).

H264 hardware decoding is only supported up to HD resolution on RPi0-4. Only HEVC works with hw decoding of 4k files on RPi4.

But keep in mind that some of the high-bitrate 60fps HEVC demo clips won't play smooth (this is a known issue), standard 4k 24-30fps files should be fine though.

Download is working fine here but it could be that one of the download mirrors is having issues.

Please provide a debug log, without that there's nothing we can do as we don't know what's going wrong (or which mirror may be having issues, if that's the case).

LE 9.2.5 firmware is ready for USB boot, no need to replace firmware files.
