Hello I am running my 7640u framework on 22h2 19045.6226 Windows 10. Somehow the two usb c expansion cards do not detect my external ssd but the usb a works. The drive gets detected on another laptop and desktop. Any suggested solutions? Edit: drive gets detected if plugged directly into the mo…

Doesn’t get detected on ports 1 & 3 but works fine on 2 & 4. Works if plugged directly into the mb usb4 ports. On latest bios and driver package with the latest amd win10 drivers. I am using a tuf a1 ssd enclosure with the latest firmware.

Look for a setting in the BIOS called “measure USB” or something like that. If it is disabled, it will not boot from it.

Hello, this is not a boot device.

Hi, I have gone into details about reason on another thread: [image] USB-C Problems with USB-PD cycling every second (ANG) Framework Laptop 16 Some points to note about the 22k vs 10k resistor pullup (Rp) and its potential affects on devices. 22k results in…

I think, if cables were the root cause it then the drive wouldn’t have been detected if plugged directly into the motherboard usb port, bypassing the USBC expansion card. The the cable works with the usb expansion cards works on the usb 3.2 ports, but not the usb4 ports.

I don’t think I understand how you have it linked up. Maybe you could explain it a little differently and I might understand, I don’t know.

The external ssd doesn’t get detected when plugged into the usbc expansion card with the usb4 ports. If the external drive is plugged into usbc/usba expansion cards in the usb3.2 ports, it gets detected. If I bypass the type c expansion card and insert the external drive directly into the usb4 port…

I think I understand now. That leaves two options: Your usb-c expansion card is faulty, check a different usb-c card if you have one. Maybe, in general all usb-c expansion cards add unnecessary noise to the signal. So a better usb-c cable would help, but the real fix might be better designed …

The USBC expansion card works when plugged into the usb3.2 ports.

Hi,

I have gone into details about reason on another thread:

Essentially, the FW might be more susceptible to noise than other laptops.

The work around is to purchase a better USB-C cable. I have found 40bps Thunderbolt cables to work well.
