Device Connection Limits

Panda itself has no limit on connected devices. The limit is from your hardware.

USB connection mode:

• Ordinary home computer: max ~40 USB connections (motherboard limitation)
• Commercial server (X79/X99 architecture): no limit in theory

OTG or WiFi connection mode:

• Home routers: max ~20 devices stable
• Enterprise routers: max ~40 devices stable
• Soft routing: supports hundreds of devices (requires sufficient bandwidth)

Device Cannot Be Detected?

Check if the computer recognizes the device first. If the computer doesn't recognize it, the software can't either.

Common causes:

1. USB debugging not turned on
2. Phone driver not installed
3. ADB conflict (multiple different versions of Adb.exe in the system)

USB Controller Resources Insufficient?

1. Turn off [XHCI] under [USB] in [BIOS]
2. Try changing the USB port
3. Use a specific USB expansion card (one card can carry ~15 devices)

Panda Says "Not Authorized"?

1. Get the ADB authorization file (adbkey, adbkey.pub) from the merchant
2. Put files in C:\Users\Administrator\.android folder, overwrite, restart computer

1. Reduce frame rate of the small screen to minimum
2. Check if [Random Delay] switch is on - turn it off
3. Check if [Synchronization Delay] switch is on - turn it off
4. Upgrade computer configuration (more CPU cores = smoother)
5. Try updating the data cable (transmission rate may be too low)
