- Short answer
- Shopify’s Hub page names no one cause for every dropout — run its checks (reseat cables, cut Hub power for 10 seconds), then fix the status shown.
- Error status
- Close and reopen Shopify POS, then restart the Hub; still Error, restart the iPad or Android tablet.
- Could not connect
- Documented for iPad pairing: iPadOS 18+, bottom tablet port; on Lightning iPads, a POS Hub Lightning cable, not an adapter.
- Firmware 0.0.0
- Or an all-zero serial: the Hub isn’t communicating correctly; restart it and the tablet at the same time.
- Factory reset
- Checks and fix failed: tap the firmware number 3 times within 2 seconds, or hold the pinhole button 10 seconds.
What should you check first when the POS Hub disconnects?
No Shopify page we read on September 23, 2026 (POS Hub, POS troubleshooting, tablet stands, the Hub's store listing) gives one cause for every dropout; the Hub page sets an order: seven general checks first.
- A compatible device — the Hub doesn't work with the POS Tablet Stand.
- Replug the USB device, or try another Hub port.
- Replug the Hub into the tablet.
- Unplug the Hub's power for 10 seconds.
- Power-cycle powered USB devices.
- Try a different cable.
- Plug the Hub straight into the tablet, not through another USB hub.
On a Lightning iPad, Shopify's setup steps warn that adapters “can cause intermittent pairing and connection issues.”
Switching a connected keyboard to a barcode scanner, or back, also drops the Hub for a moment: it “briefly disconnects when it reconfigures itself.”
How do you fix Error, “Could not connect” or firmware 0.0.0?
Error that won't clear: close and reopen Shopify POS, restart the Hub (power out for 10 seconds). Still Error? Restart the iPad or Android tablet:
If the operating system stops communicating correctly with connected USB hardware, then restarting your tablet can reset the connection.
“Could not connect to POS Hub” when pairing an iPad: check iPadOS 18 or higher, the cable in the Hub's bottom tablet port, an updated POS app and, on Lightning iPads, a Shopify POS Hub Lightning cable, not an adapter. Then restart the Hub and iPad together.
Firmware 0.0.0 or an all-zero serial means the Hub isn't communicating correctly with your tablet: cut its power for 10 seconds and restart the tablet meanwhile.
When should you factory reset the POS Hub, and how?
If the checks and the fix both fail, you might need a factory reset. Both ways start with the Connectivity icon, then the Hub.
In the app: tap the Hub's firmware version 3 times within 2 seconds, confirm Reset POS Hub, and allow up to 6 minutes.
With the pinhole button: choose Forget POS Hub, turn off your POS device, hold the pinhole button for 10 seconds, turn the device on once the Hub restarts, and reconnect it.
