Re: [Trisquel-users] boot-up USB memory card not working ...

Seems like compatibility issue with the USB storage media. I tried many  
portable HDDs, flash disks and card readers on coreboot, and found only a  
small portion of such devices work with coreboot. Maybe you can invite your  
friends to try their USB storage devices and see which can be recognized by  
libreboot and then buy the proven working models?

Note: this compatibility issue was quite common when USB 3.x was initially  
introduced. I wanted to create a USB 3.0 live disk, but only succeeded in  
booting from it after a long trial and error process. Many of the USB storage  
media I tested weren't recognized by BIOS, or even caused the POST fail.
