Problem with usb open on rtl

[virtualrobotix]

Dear Friends, i'm try to test the project but when try to open the usb port with rtl_fsk or rtl_sdr i have this error .

na_gain: 15 mixer_gain: 15 vga_gain: 8 Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM

Kernel driver is active, or device is claimed by second instance of librtlsdr. In the first case, please either detach or blacklist the kernel module (dvb_usb_rtl28xxu), or enable automatic detaching at compile time.

usb_claim_interface error -6 Failed to open rtlsdr device #0.

If i use the standard version of rtl_sdr it work with same hardware without problem . Do you have some suggestion can help me please. Best Roberto
