5 years ago I have executed rpi-update but still has the same problem. If all 3 devices are plugged in the hub, no 1.1 USB device, all are USB 2.0. The USB HDD connected directly to the Pi will get a USB disconnect and will result in the OS crashing due to I/O errors. Again, the USB hub has an isolated PSU and it does not backfeed. The Pi has the official PSU.
I have unplugged the USB 3G dongle from the hub and the HDD does not disconenct anymore.
Here is the dmesg for the working part (2 devices to USB Hub, USB DVB-T and USB webcam both are USB 2.0 as shown on lsusb -vvv|grep bcdUSB)
sudo dmesg

Pi3B+ ports USB port 1 = USB hub data and gnd, USB port 2 = USB y cable for HDD SATA USB USB port 3 = USB WiFi ralink USB port 4 = USB y cable for HDD SATA USB
I have also tried the following combination to avoid the errors:
Conf1: USB HUB Plugged in = webcam, DVB-T, WLAN, USB 3G PI pugged in = USB HDD and USB Hubdata Result: HDD I/O error and disconnection on bootup.
conf 2: HUB: Webcam, DVB-T, USB 3G PI: WLAN, USB HDD, USB HUB data Result: I/O error on boot if not, random HDD disconnect after boot
conf3: HUB: USB 3G, Webcam ,WLAN PI: USB HDD, USB HUB, USB DVB-t Result: WLAN no IP assignment (no dhcp lease) but wpa_supplicants reports associated to my AP),random hdd disonnect on boot
conf4: HUB: 3G, WLAN, DVB-T PI: HDD, webcam Result: WLAN no dhcp lease but wpa_suppli is associated.NYET error in dmesg with some lan78xx messages
Conf 5: HUB: DVB-T, WLAN, Webcam PI: USB HDD, USB HUB, USB 3G Result: No WLAN IP lease, EXT4 delayed allocation data will be lost errors in dmesg
Conf 6: HUB: DVB-T, WLAN, 3G PI: USB HDD USB HUB, USB WEBCAM Result: I/O error hdd disconnect, no ip lease in wlan
Conf 7: HUB: USB DVB-T and USB Webcam PI: USB HDD, USB HUB, USB WLAN Result: Some usb disconnect on boot but no HDD disconnects, uptime is around 9 hours. But, USB 3G is not used in this setup.
USB HUB: has 2 single TT devices. All USB devices DVB-T, WLAN, Webcam, USB HDD are USB 2.0 according to lsusb -vvv Firmware hash:

Any possible fix to make the 3G dongle work? Any dwc.otg hacks?
Thanks
I have this 7 port USB hub that is powered externally, I have fixed the backfeeding problem and now faces a new problem that may be because of the Single TT hub.
Reference image: http://www.whatimade.today/how-to-protect-a-rasperry-pi-from-a-powered-usb-hub/
Here is my setup: Raspberry PI 3B+, Official Power Supply
USB SATA HDD [with a USB y-cable] as the root of the Pi. The USB SATA HDD does not boot without SD card, i have created a boot partition to make it work on a microSD. Yes, the 5 sec timeout does not work, the HDD spins after 6 seconds.
USB WLan Ralink
This 7 port USB hub, it was backfeeding but I fixed it by adding a tape to the 5V+ USB plug line.
Information to the USB Hub:
The 7 port hub has 2 single TT devices.
The Hub has the following devices plugged in:
The problem: Whenever I try to plug all those devices and start the Pi, the USB SATA HDD disconnects randomly either before boot or after booting. THere are messages about NYET on the pi from the lan78xx. More error logs to be uploaded later, since it is already midnight in my time zone.
Here is a dmesg output:
This issue may be related to: https://github.com/raspberrypi/linux/issues/2734
Should I rpi-update?
Thank You
