Yes. We are using a N210 and the memory limits have been updated to 50M. Interesting to hear that it works with Ubuntu17, tho we would like to stick with Debian. Any other ideas or queations? Meelis 8. sept 2017 6:46 PM kirjutas kuupäeval : > The original e-mail reporting "trouble" didn't specif

The original e-mail reporting "trouble" didn't specify which USRP device was involved, so in the interests of clarification and completeness, I thought that I'd interject about USB devices. Yes, the N2xx and X3xx devices use a 1GiGe (or optionally 10GiGe for X3xx) for connecting to the host comput
