Other than bottlenecking the speed are there any reasons not to do this?

also, would I lose access to say keyboard at boot if it was at the end of the hub chain?
 
power draw could be an issue, depending on exactly what's connected. Unless the hubs are powered, you might find you have issue exceeding USB current limits (500mA??)
 
Would definitely connect keyboard directly to mobo, because it's definitely uncertain in what time that whole chain would be initialized.

As option most motherboard have unused USB2 header or two.
So you might be able to add USB ports to I/O slot covers.
Though if those aren't from chipset, it's open if they work in BIOS/POST phase.
 
So the set up is as follows
Lenovo m93p mini/picro pc
2x ports on front (BT5 dongle and Wifi dongle)
3x ports on the back (USB/HDMI KVM hub) - (USB HDD) - (powered USB hub) <hub is used mainly for connecting phones, gamepads and thumb drives>

there are times that I will connect up to three other USB HDDs one of which has a 3port hub
I also sometimes use instead of the wifi a USB to ethernet device when I need to access 2 networks

I'm looking at getting one of the USB docking station/hubs so I can get an extra monitor out and another LAN connection and was just thinking of the best way to set things up and potentially make them permanent as the performance over the LAN isn't great.

the three other drives which I sometimes connect to this pc are connected to an old NAS drive that has a USB port so the HDD with the hub goes in that and the other 2 drives connect to the hub of the first drive.

I feel like im rambling on... sorry, so tired :(
 
Corsair peripherals (keyboard, bungee) get disconnected from iCue, when going into their configs, if not directly connected to the PC.

Steelseries mouse cannot update FW if not directly connected, too.

It's rubbish why these peripherals are developed to be so inflexible.

I agree with them being rubbish. I have a 20 port sabrent USB 3 hub with it's own power, and even that has trouble with 9 USB drives (each with their own power brick) and a bunch of peripherals connected. They all seem to power on but the computer starts going crazy with the USB connect/disconnect chime

Yeah there's this horrible limitation of USB endpoints that different chipsets can support.
USB 3 supports even fewer endpoints than USB 2 does. And Intel chipsets support fewer than AMD for some reason. Overloading an endpoint limit causes stuff to fight to be registered. And I found no way yet to see how many endpoints a device uses, to plan connections accordingly... edit: media devices (webcams, usb headphones) use loads more endpoints compared to control devices.

i have heard.. though not tested yet (i may do when i make some changes to one of my rigs), if you connect your hub directly to an internal USB header, that helps mitigate the issue.. but that resolution came up often to resolve the issue with the Command Pro randomly disconnecting
