Ok so this just started the other day, my quest 2 will no longer charge via the Oculus link cable, and when I play PCVR the Q2 battery is discharging fast, I'm talking lost 40% charge in 10 mins.
After playing around I have found a strange issue, the link is plugged into the USB C on my MoBo and when checking power outputs for USB ports the Quest 2 port is showing 0 power output, yet the link cable works fine just stopped supplying power all of a sudden.
unsure if this is a software issue in my PC, It charges fine via a wall socket
So far, I unplugged everything from other USB ports, no luck
Plug my Pixel phone into the link cable and it gets a power reading of 896 mA
Tested in a USB 3 port and the Q2 shows 500mA
Tested on another USB c-c in same USB C port and same issue 0 power output
Mobo is only 3 months old ROG Strix B550-F Gaming
if anyone knows a possible solution?
Updated with another test:
Using power cord that came with Q2, plugged into USB C port on back of PC, Phone plugged in reads 500mA, plug Q2 in and reads 0mA
Yup, same issue here.
Updated bios, chipsets, drivers, nothing worked. Even tried fresh windows install. I am starting to wonder if it is an ASUS issue or Oculus. I have a TUF gaming x570 pro (wi-fi) motherboard and I am experiencing the same exact problem. 0 mA read in USBdeview with either usb C port but other devices give power. Computer is also only two months old.
It's a common bug for v26. I don't think Oculus is going to fix this.
v25 and v26 contains a lot of bugs that ruins the Quest 2 device. Worst case is bricking the device and no way to recover, best case is just Oculus Link problems (not charging, etc) and controller tracking delay increased. So you are lucky, just got oculus link not charging problem. Mine got Oculus Link not charging, random black screen frame, lost controller tracking, and significantly increased controller tracking latency that makes Beat Saber hard to play.
