I have an SSD and a USB drive plugged into my iMac. They work fine. Unfortunately when I reboot they are not recognized until I manually unplug and plug them back in. Does anyone know how to fix this glitch?

Disconnect all other external devices to see if one of them is causing a problem. It is known that a Wacom tablet can prevent the mounting of some external drives, but the same may also occur with other connected devices. I've seen reports that disconnecting the Wacom tablet will allow the drives to mount, then connecting the Wacom tablet to use both the devices.
Also, make sure the drives are connected directly to the Mac since some adapters, docks, & hubs may cause problems.
Try booting into Safe Mode to see if you encounter the same issues. Keep in mind Safe Mode disables third party drivers from launching so if your external drives are utilizing the manufacturer's proprietary software, the drives may not mount.
What is the exact model of your Mac? You can get this information by clicking the Apple menu and selecting "About This Mac". Also what are the make & models of the affected drives and the file systems on them? Do they have their own dedicated power supply or do they rely on bus power? This is all information that should be provided when asking for assistance.

Are they connected directly to the Mac or through a hub or dock? If not directly, try that for both. If you need a USB-C to USB-A adapter, Apple sells a good one.
They are connected directly to my iMac. I am running the latest Monterey OS.
