January 3, 20251 yr I’m currently using Unraid with the Unassigned Devices plugin to manage external drives. The NAS easily recognizes HDDs connected via USB-A immediately after plugging them in, but SSDs connected via USB-C are only recognized after rebooting the entire system. Steps Taken: Verified the SSD and USB-C cable are functioning correctly on other systems. Ensured the Unassigned Devices plugin is updated to the latest version. Checked Unraid logs for any errors or unrecognized device messages when plugging in the SSD via USB-C. Issue Persistence: USB-C SSDs remain unrecognized until a full reboot of the NAS. USB-A HDDs work flawlessly without requiring a reboot. Question: Is there a way to fix this issue so USB-C SSDs are recognized immediately after being plugged in, without the need to reboot? Could it be related to driver support, power delivery differences between USB-A and USB-C, or a configuration setting in Unraid?
January 4, 20251 yr Community Expert There's no setting for that, possibly chipset/USB controller related, post the diags after first connecting the device and then after a reboot when they are recognized.
January 5, 20251 yr Author So the first file is connecting the device before rebooting and the second file is after rebooting, I hope this helps.. sexybard-diagnostics-20250105-0028.zip sexybard-diagnostics-20250105-0031.zip

January 5, 20251 yr Author thanks Jorge, I'm a bit of a noob when it comes to all this, could you specify what you mean by v7? Version 7? to update unraid?
