Seeing the passthrough comment reminded me I have a weird issue with my usb wlan nic doing something odd, might affect you doing much the same. I forget the flavor of nic, but once I plug it into linux, the drivers would kick in and start locking the device. My goal usually with it is to tend to a windoze instance that also runs some wireless spectrum analyzer tools, but I end up having to rmmod the driver prior to giving it to virtualbox or windows just sees it as a broken driver state with the angry (!). Might be something like that why it doesn't always come and go? -mb On Thu, Apr 13, 2017 at 3:04 PM, Jerry Snitselaar wrote: > > Stephen M @ 2017-04-13 04:45 GMT: > > I went and picked one of these up at Fry's since they were $10. > Using usb passthrough from my fedora host to the ubuntu vm, I > can get the device to come up with either the r8188eu driver that > comes with Ubuntu, or the 8188eu driver that tp-link provides. > > One thing I had to do when rebooting the vm was remove and reinsert > the device, but that could just be an issue with using it through > usb passthrough. > > This is with 14.04.3 running 3.19.0-25-generic > > Perhaps if you want to use the tp-link provided one, maybe blacklist > the Ubuntu driver. > > snits > > > > jsnitsel@ubuntu14-32:~$ lsmod | grep 8188 > jsnitsel@ubuntu14-32:~$ lsusb > Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. > Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd > Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub > Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub > Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub > Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub > jsnitsel@ubuntu14-32:~$ find /lib/modules -type f -name 8188eu.ko > jsnitsel@ubuntu14-32:~$ cd Downloads/Driver/ > jsnitsel@ubuntu14-32:~/Downloads/Driver$ ls > 8188eu.ko 8188eu.o core include modules.order platform > wpa_0_8.conf > 8188eu.mod.c bin hal Kconfig Module.symvers runwpa > 8188eu.mod.o clean ifcfg-wlan0 Makefile os_dep wlan0dhcp > jsnitsel@ubuntu14-32:~/Downloads/Driver$ sudo cp 8188eu.ko > /lib/modules/`uname -r`/extra/ > [sudo] password for jsnitsel: > jsnitsel@ubuntu14-32:~/Downloads/Driver$ sudo depmod -a > jsnitsel@ubuntu14-32:~/Downloads/Driver$ > jsnitsel@ubuntu14-32:~/Downloads/Driver$ sudo modprobe 8188eu > jsnitsel@ubuntu14-32:~/Downloads/Driver$ ip a show > 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group > default > link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 > inet 127.0.0.1/8 scope host lo > valid_lft forever preferred_lft forever > inet6 ::1/128 scope host > valid_lft forever preferred_lft forever > 2: eth0: mtu 1500 qdisc pfifo_fast > state UP group default qlen 1000 > link/ether 52:54:00:e0:39:64 brd ff:ff:ff:ff:ff:ff > inet6 fe80::5054:ff:fee0:3964/64 scope link > valid_lft forever preferred_lft forever > 3: wlan0: mtu 1500 qdisc mq state UP > group default qlen 1000 > link/ether d4:6e:0e:19:87:a3 brd ff:ff:ff:ff:ff:ff > inet 192.168.1.163/24 brd 192.168.1.255 scope global wlan0 > valid_lft forever preferred_lft forever > inet6 fe80::d66e:eff:fe19:87a3/64 scope link > valid_lft forever preferred_lft forever > jsnitsel@ubuntu14-32:~/Downloads/Driver$ cd /sys/class/net/wlan0/device > jsnitsel@ubuntu14-32:/sys/class/net/wlan0/device$ cat uevent > DEVTYPE=usb_interface > DRIVER=rtl8188eu > PRODUCT=bda/8179/0 > TYPE=0/0/0 > INTERFACE=255/255/255 > MODALIAS=usb:v0BDAp8179d0000dc00dsc00dp00icFFiscFFipFFin00 > jsnitsel@ubuntu14-32:/sys/class/net/wlan0/device$ lsmod | grep 8188 > 8188eu 933888 0 > cfg80211 450560 1 8188eu > jsnitsel@ubuntu14-32:/sys/class/net/wlan0/device$ ping -c 5 google.com > PING google.com (216.58.217.206) 56(84) bytes of data. > 64 bytes from lax17s05-in-f14.1e100.net (216.58.217.206): icmp_seq=1 > ttl=55 time=23.6 ms > 64 bytes from lax17s05-in-f14.1e100.net (216.58.217.206): icmp_seq=2 > ttl=55 time=29.9 ms > 64 bytes from lax17s05-in-f14.1e100.net (216.58.217.206): icmp_seq=3 > ttl=55 time=28.3 ms > 64 bytes from lax17s05-in-f14.1e100.net (216.58.217.206): icmp_seq=4 > ttl=55 time=22.0 ms > 64 bytes from lax17s05-in-f14.1e100.net (216.58.217.206): icmp_seq=5 > ttl=55 time=22.6 ms > > --- google.com ping statistics --- > 5 packets transmitted, 5 received, 0% packet loss, time 4005ms > rtt min/avg/max/mdev = 22.064/25.314/29.975/3.209 ms > jsnitsel@ubuntu14-32:/sys/class/net/wlan0/device$ uname -r > 3.19.0-25-generic > jsnitsel@ubuntu14-32:/sys/class/net/wlan0/device$ find /lib/modules -type > f -name 8188eu.ko > /lib/modules/3.19.0-25-generic/extra/8188eu.ko > jsnitsel@ubuntu14-32:~$ cd /etc/modprobe.d/ > jsnitsel@ubuntu14-32:/etc/modprobe.d$ cat blacklist-r8188eu.conf > blacklist r8188eu > > --------------------------------------------------- > PLUG-discuss mailing list - PLUG-discuss@lists.phxlinux.org > To subscribe, unsubscribe, or to change your mail settings: > http://lists.phxlinux.org/mailman/listinfo/plug-discuss
