I've had the similar problem of my Kobo failing to mount on my Mac
Setup- Kobo Aura H20 edition 2 (s/w ver 4.26.16704)
- MacBook Pro (Retina, 15-inch, Mid 2015)
- Mac OS X 10.14.6 (Mojave)
Symptoms
When plugged in with any USB cable (old style rectangular USB-A to micro-USB),
The Kobo would quickly prompt: "Computer detected ... (Cancel) (Connect)",
Then report: "Connected & Charging ..."
BUT,
on the Mac there was no sign of the device appearing in any of:
- left panel of Finder windows,
- ${YourComputerName} folder in the Finder
(the one that usually contains Network, MacintoshHD, Remote Disk)
- output from the `mount` Terminal command
- "USB" section of the System Information.app report (**)
(from Apple Menu: About this Mac: System Report)
- Also note that when I unplugged it the Mac did *not* complain that I should have unmounted it first
Tried different cables,
Tried different USB ports,
Tried with & without the Mac connected to power,
Tried with & without the Mac connected to other devices.
(**)
Sometimes (maybe 1 time in 8), System Information.app would report:

BUT, it still didn't mount or become visible anywhere on the Mac.
...Also notice that in the report there was NO subtending section "

((NOTE: it typically takes
fully 3-to-10 seconds for the disk / volume to show up in the Mac Finder
after the Kobo reported "Connected and charging".))
Part 1: LEFT port only!
Believe it or not which USB port you use from your Mac *can* matter (depending on your mac model)!
It's hard to find infomation online, but different USB ports can have different power-delivery characteristics.
For my machine only the
LEFT side USB port worked, not the right.
I checked more than 5 times on each side, and the results were consistent!
For any issue this subtle / finicky, you should also be sure that:[LIST=1][*]No other peripherals are connected,[*]your mac is plugged in to power,[*]use the *correct* power adapter, (for me this was an 85W MagSafe-2 brick, not the newer 60W bricks that are more common)
Part 2: Connect via an exernal USB 2.0 hub!
What finally worked for me was connecting through a old USB 2.0 HUB that I found in the bottom of the disused cables, connectors, & chargers drawer:
Targus brand travel USB hub, model ACH112US
I connected the HUB only to the Mac & the Kobo, not to it's own external power brick -- that was lost long ago
