TL-WN350G has Atheros AR2417 chipset
Use ath5k module,no firmware needed
Install linux-wireless.tazpkg which has ath5k module
Follow this: http://doc.slitaz.org/en:guides:wifi-easy

Thanks mojo for your time and your reply:

Is correct, the card is supported, but I can not connect for the public red

Which is the reason?

In "tazhwbox" displays the following information:

ath5k support for Atheros 5xxx of land 802.11 wireless card
rtl8187/rtl8187b rtl8187 wireless usb driver

Which is the reason for this ghost usb driver???

Other information from my machine is this:

There is a bug with whatever system in linux identifys/loads driver module for the AR2417/AR5007G chipset.
The system loads rtl8187 and ath5k instead of just athk5
Do not use tazhw/autodetection to load the module for the wireless card
Maybe it will work if you only load ath5k ?
Try this:

tux@slitaz: subox wifibox

Drivers tab,module: ath5k,click Load.verify only ath5k is loaded with lsmod button.
Use networks,favorites,configuration tabs to setup connection.
If connection works:
Add ath5k to /etc/rcS.conf LOAD_MODULES=
Edit /etc/network.conf for default interface , enable wifi at boot, etc.
