Hello,
I’m currently troubleshooting the Coral USB on two different devices, essentially starting fresh on both. However, I’m encountering an issue where it remains identified as Global Unichip Corp. rather than transitioning to Google Inc.
Here’s the breakdown of the systems:
- Computer 1 - Intel i7 4790 running Proxmox 8.1.3
- Computer 2 - Intel i7 4470k running Proxmox 8.1.3
- Computer 3 - Intel i7 10800u running Windows 11 (Laptop)
Here are the steps I’ve taken:
Computer 1:
- Installed the Coral drivers, re-plugged the device, rebooted the system, and even attempted running a LXC container with the tteck script. Despite these efforts, the state remains unchanged.
Computer 2:
- Installed the Coral USB drivers prior to plugging in the TPU, re-plugged the device, and rebooted the system. However, it’s still detected as Global Unichip Corp.

Computer 3:
- Interestingly, when I used the same Coral USB on a Windows environment, after installing the drivers, it successfully transitions to Google Inc.
I’m puzzled by the discrepancy between Computer 3 and the others. Any insights or suggestions would be greatly appreciated.
I’m not sure, I had my usb coral working in proxmox for a months in a proxmox VM and I know it sait Google inc. I put in new hardware a few weeks ago, rebuilt things a bit, moved from a separate frigate VM to just using the add-in. When I went to map the coral over I get the same thing, Global Unichip. It works fine for me, so I kind of ignored the change.
Dear all,
this is just to summarize my experience with Coral + Proxmox + HA guest on my rather old Xeon/Intel system.
I spend several hours (around 10) to get the setup working. Despite the common tips and tricks and around 10 different parameters and factors that I tried (boot parameters about iommu, vfio-pci, pcie_aspm, several bios options for PCIE gen1/2/3 and apsm power management) I found a root cause in much simpler things:
The root cause for the device not working properly (it was always detected, but did give errors on memory timeout etc.) was physical:
- I had chosen the wrong PCI slot – one seems to only support Gen2, whereas Gen3 was needed due to MSI-X support that needs to be enabled. My mainboard is an Supermicro X10SLM-F and I needed to use the “big slot”.
- I had bought a cheap “riser card” from AliE, which was basically a ribbon cable attached to two plugs/sockets. It seems this changed the timing of the card quite a bit, so it did not run stable at all. Even when I had changed 1, the device worked for about 5 minutes and then stopped service.
I have now bought a good quality riser cable, which seems to be rock solid (very short cable) for 11 euro at Amazon. It works for a day now without flaw.
My configuration is:
boot options in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="pcie_aspm=off vfio-pci.ids=1ac1:089a"
Modprobe Options
# cat blacklist-apex.conf
blacklist gasket
blacklist apex
options vfio-pci ids=1ac1:089a
The device used to be on 04:00 and switched to 01:00 when I changed slots. I have mapped the PCI device within promox and I run HA OS within the VM.
In some configurations I had very weird effects: The system was very very very slow (boot time of 5 minutes) and sometimes froze. I have no idea what caused it (kernel params pcie_aspm and iommu possibly), but it went away when changing parameters and pci slots.
My Bios is back on defaults (Gen3 for all PCI).
I have not changed boot options or alike within the HA OS guest.
