Clover compact works, sometimes (Clover USB Port shuts down Approximately 1–2 minutes after startup)

[jjone]

The main issue happens after the Windows computer goes to sleep and wakes up.

Symptoms:

Clover Compact remains physically connected via USB
After Windows wake-up, Clover Compact no longer appears in Windows Device Manager
"Scan for hardware changes" does not detect it
Unplugging and reconnecting the USB cable does not help
The only way to recover the device is rebooting the Clover Compact

Question:
Why does the Clover Compact USB device disappear after Windows sleep/wake?

[jjone]

The problem is not related to Windows sleep/wake.

Observed behavior:

After Clover Compact boots, Windows Device Manager detects "Clover Compact Merchant Mode".
Approximately 1–2 minutes after startup, the Clover USB interface appears to shut down or disconnect automatically.
The device only switches to "Clover Compact Consumer Mode" if the semi-integration application sends its initialization commands before this timeout.
Once the USB interface shuts down, the device disappears from Windows Device Manager.
Unplugging/replugging the USB cable and rescanning for hardware does not restore the device.
The only recovery method is rebooting the Clover Compact.

Expected behavior:

The Clover Compact USB interface should remain available after boot, regardless of whether initialization commands have been sent.
The host application should be able to connect and initialize the device at any time without requiring a Clover reboot.

Can you confirm whether this USB timeout behavior is expected, or if there is a configuration or firmware setting that keeps the USB interface active continuously?

Additional findings:

After Clover Compact boots, its USB interface remains available for approximately 1–2 minutes. During this period, Windows can detect the device and the semi-integration application can initialize it.

After the timeout expires:

The Clover USB device disappears from Windows Device Manager.
The USB interface appears to be disabled on the Clover side.
Unplugging and reconnecting the USB cable does not re-enable the USB interface.
Opening the USB Pay Display app does not re-enable the USB interface.
Rescanning hardware in Windows does not re-enable the USB interface.
The only way to restore USB connectivity is rebooting the Clover Compact.

Expected behavior:

Connecting a USB cable from the Clover Compact to a host computer should re-enable the USB interface and trigger USB enumeration.
Opening the USB Pay Display application should re-enable the USB interface if it was previously disabled.
The USB interface should remain available continuously, or at minimum be recoverable without requiring a Clover Compact reboot.

Currently, after the USB timeout occurs, the user must reboot the Clover Compact to obtain another 1–2 minute window where the USB interface is available.
