USB bluetooth
Nazdar, zkoušel jsem připojit nějaký BT USB adapter Gellink, ale nejsem si jistý, jestli není rozbitý.
Dá se něco vyčíst z dmesg?

Nevím, možná by to prověřili, kdyby si to brali do kosmické stanice, ale jinak v tom nevidím šanci. Navíc poštovné do USA by bylo drahé.
No nic, prověřil jsem to ve Windows, kde to bluetooth nainstalovalo, i přes to ,že to našlo asi jen ůlku ovladačů, tak to šlape. Zřejmě nějaký bordel v linuxu.
