Environment
- App Control Server: 8.0 P4 - 8.6.x
Symptoms
- Device shows "Removable Device: No"
- Device experiencing blocks by the rule "Block writes to unapproved removable devices"
Cause
Known issue with recognizing USB Attached SCSI (UAS) Mass Storage Device Drivers incorrectly.
Resolution
- Find the host ID of the endpoint experiencing the blocks
- Login to the App Control database server
- Identify the device_id of the problematic USB device:
SELECT * FROM das.dbo.devices WITH (NOLOCK) WHERE host_id='InsertHostIDHere'
- Set the drive to removable:
UPDATE devices SET is_removable=1 WHERE device_id=InsertDeviceIDHere
Additional Notes
In 8.6+ we correctly identify these devices as removable (EP-7979). Devices affected prior to upgrade will need manually corrected.
