I am having a similar problem with both of my Banana Pi units.
For context, my Ban Pro devices detect and mount USB HDDs. My RasPi B+ and v2B+ devices with powered Raspiado USB add-on boards also detect and mount these drives. (I don't attempt to run USB-powered HDDs on Ras Pi units bc those are known to be problematic - they mount but throw errors and fail on read/write).
With the Ban Pi devices, however, I have tried both a USB HDD (Western Digital) and USB thumb drive (Sandisk). Both storage devices are found and mounted on my Mac and other "pi" units. Neither is detected or mounted on either of my Ban Pi v1. Curiously running lsusb as root shows both of these devices. Thus they are being detected at the USB controller. Also the "lights" on both devices come on normally. I've put a PiHut powered USB hub between the Ban Pi and drives - working on the same theory that drives using the Raspiado boards on the Ras Pi B+ and v2B+ units). Same results.
I suspect this is either a power or driver problem. I have used the Pi Hut powered USB hub to run drives on Ras Pi machines before, so I'm puzzled. Also I've used this drive before enough - and checked the format on my Mac - so I'm looking to the Ban Pi v1 as opposed to the HDD. The USB stick, though, baffles me. Even if that HDD were too much for the Ban Pi USB, the thumb drive should work. I've used in on Pi's as a go-to temp storage utility drive. My OS is Raspbian downloaded from the Ban Pi downloads in the last few days. I performed apt-get update and upgrade on both Ban Pi units before starting on my config work today.
Can anyone suggest a solution or things I should look at next??
Edit since initial post: I have checked dmesg by plugging in the USB thumb drive after a clean reboot, while logged in. No errors, although the last message says "usb 2-1: new high-speed usb device num er 2 using ehci-platform". When I pull the thumb, I see "usb-2-1: usb disconnect, device number 2". When I plug in the HDD, I see "usb 2-1: new high-speed usb device num er 3 using ehci-platform". Messages confirm what I found earlier: usb subsystem sees the devices - and appear to do so without errors. Am I seeing a driver problem caused by my update/upgrade?
Second update: no device is being created in /dev when either device is inserted.
Third update: I swapped a Raspiado USB add on card over to one of my Ban Pi units. Raspiado is externally powered by a reliable bench supply that displays volts, amps, watts - same Raspiado and bench supply used to test these drives on a Ras Pi B+ where both mounted. Same result as above - no device created, no drive mounted, nothing showing up above the USB level. Same device messages in dmesg.
