CY7C65640 USB 2.0 hub driver

I have a Digitus DA-70133 4 - Port - USB 2.0 Front Panel Hub based on a Cypress Semiconductor Corp. CY7C65640-LFXC USB-2.0 "TetraHub" chip.

According to the informations on the Digitus page the hub should work in Windows 98. The problem is, it is detected as an unknown USB device. So, I'm looking for a correct driver.

My computer does not have USB 2.0 ports, but it should work on USB 1.1, I think.

So far, all USB hubs I've had were working without any additional drivers.

Anyways, I want to make the hub working with Windows 98.

do you have Windows 98 second edition (at least)? without that, it will be difficult to get it working if at all

Yes, it is a Windows 98 SE system case.

I failed to find any Windows 98 drivers, so far.

The DA-70123 = "USB Sharing Switch 2PC - 1 Device".

The DA-70133 = "USB 2.0 Hub, 4 Port, 3.5" Type for Front Panel"

It does not look like a DA-70123 driver could be good for a DA-70133, I'm afraid.

Well, other USB devices are working correctly. But, the DA-70133 hub is detected as an unknown USB device. That's why, I believe it is a driver problem.

As far as I know, the Uhcd.sys update is for AMD processor and VIA chipsets. But, my computer is equipped with Intel 815 series chipset and Intel Pentium III 933 Mzh processor.

Well, I have this driver installed, already. Because, I'm using an USB external drive on this computer. That's why, I know the USB port works correctly.

The problem with this particular motherboars is, it does not supply enough power to run the USB disk without an additional power supply. The DA-70133 USB hub have a sufficient power output to run the USB disk on USB power only (I tested it on a Windows XP computer). That's why, I want to use the DA-70133.

You say you have the drive installed.

Have you tried going to Device Manager, and go to the properties of the unknown USB device, click to change driver and force it to install the correct one?

Regarding the USB power be aware that it is motherboard dependent and not OS, but running an Intel chipset is usually good enough. VIA had huge problems with USB power.

Personally I would go for a self powered hub, but hopefully we will get a solution for you.

Good luck,

Zee

The DA-70133 is a self powered hub. It takes power from a FDD type power connector.

That's it. To force a "USB root hub" driver. And,... it works.
