Re: usb_claim_interface error -6

No I didn't - maybe I should try that! The reasons I didn't were 1. I don't know how to, 2. I was afraid that the two copies of rtl-sdr would use the same kernel module, so if I blacklisted it, the other copy wouldn't work either.

Would you happen to know how to blacklist a kernel module?

usb_claim_interface error -6

I've installed rtl-sdr on a raspberry pi.
