    issue with RT3070 chipset

    I did check the recommended cards list and one of them was RT3070

    The card seems to be working out of the box, it is recognized
    and kind of installed
    it also goes in to the monitoring mode
    BUT airodump-ng can not display anything when scanning
    airodump-ng wlan0mon
    Here are the needed details:

    @kali:~# lsusb
    Bus 001 Device 002: ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter

    Bus 002 Device 004: ID 0e0f:0008 VMware, Inc.

    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

    and dmsg:

    Now here is how it goes in to the monitoring mode:

    @kali:~# airmon-ng check kill && airmon-ng start wlan0

    phy0	wlan0		rt2800usb	Ralink Technology, Corp. RT2870/RT3070
    		(mac80211 monitor mode vif enabled for [phy0]wlan0 on [phy0]wlan0mon)
    		(mac80211 station mode vif disabled for [phy0]wlan0)

    here what it does with

    CH 8 ][ ELAPSED: 1 min ][ 2017-04-18 16:13
    BSSID                   PWR Beacons     #Data  #/s   CH    MB    ENC    CIPHER  AUTH  ESSID
    BSSID                   STATION               PWR    Rate   Lost   Frames  Probe

    So no scan results are coming up

    I believe there is something I'm missing ...
    it works fine with Windows, scans and lists all networks...

    Could u help in this one ?

    Ok Sorted the issue,

    The Device is too powerful, by specs its High Power(5800MW) 58DBI
    I have set TX to 35 dBm , which is 3,2 W, so it seems it needed more power,
    I changed USB2 to USB3 in VMware Settings, and it works just fine,

    By the way if this spec is troth, I can increase up to 47 DBI which is
    50 W (Sounds bit unrealistic ) but question is what is Safe no "Self harm" limit ?
