OK, just tried my WD09 FileHub with a powered hub (a HooToo USB-C hub with adapter) attached with a 512GB SSD a 128GB flash drive (both Samsung and formatted exFAT) and was able to get to everything on the storage, both with the RAVPower app and with FileBrowser. No issues.
Do you have the hub and storage attached and powered when you turn on the FileHub? Do you have the latest FileHub f/w installed?
At your suggestion I connected the powered hub with the storage attached before turning on the filehub. I turned on the filehub then connected the ipad to the filehub.
It seems that the problems are not caused by different formatting of the devices attached to the hub. I reformatted the Sandisk Cruzer flash drive so both are formatted exFAT. No changes. Only one storage is visible. Connecting the hub to a USB-A port of a Windows laptop both storage are visible.
Maybe is caused by difference between:
- rp-wd007 and rp-wd009
- your usb hub and mine
Thanks a lot for your time.
I tried too to contact ravpower support but IMHO it is poor. No way to make me understandable, no new versions for the firmware.
For now I give up.
