I went ahead and set it to the max of 500mA. USB Wi-FI adapters can draw anywhere from 100mA - 500mA, averaging around 200mA.

Just like I found in a past project using a USB webcam with the MiniZed, the Maximum VBUS Power usage was set to limit the USB port to provide no more than 2mA.

To support these kernel options as well as wireless functionality in general, I also enabled the following kernel driver packages: CONFIG_USB CONFIG_RFKILL CONFIG_MAC80211 CONFIG_RTL_CARDS CONFIG_NETDEVICES CONFIG_CFG80211_WEXT CONFIG_WLAN_VENDOR_REALTEK CONFIG_MAC80211_RC_MINSTREL CONFIG_MAC80211_RC_MINSTREL_HT CONFIG_USB_GADGET_VBUS_DRAW 500 CONFIG_MAC80211_RC_DEFAULT_MINSTREL This particular Wi-Fi module is built on the Realtek Semiconductor RTL8192CU 802.11n WLAN Adapter, which after looking up it on tells me that I need to enable the following drivers in the kernel (using the PetaLinux kernel configuration editor GUI in this case): CONFIG_WLAN CONFIG_RTLWIFI CONFIG_RTL8192CU To determine what kernel drivers needed, I've been using to search product/chip names Starting with the kernel of the Pi OS embedded Linux image, entering the kernel configuration editor: petalinux-config -c kernel – All of the above is tested with Kali 2017.2 both as a virtual machine and as a main OS.To add the compatibility in my PetaLinux project for Pi OS to support RTL8192CU chipset USB Wi-Fi adapters the kernel, root filesystem, and device tree all needed to be modified/updated. – Will work with Kali whether it is installed as a main OS or as a virtual machine (regardless of the host OS). – Realtek RTL8812AU chipset, support 802.11b/g/n/a/ac. This adapter is even featured on Kali’s 2017 release blog post, there are other wireless adapters that use this chipset but this is the one that most experts prefer and use, it is just more reliable and more stable that others that use the same chipset. This is one of the best wireless adapters ever made by Alfa to support both 2.4Ghz & 5Ghz frequencies, it uses Realtek RTL8812AU chipset which is supported by Kali 2017.1 and up.

Unfortunately, we are unable to ship this product to India.

We still ship within 1 working day but please expect delays due to Covid-19 restrictions.
