I have a drawer of spare cables collected over the years ,will a cable for a usb 1.1 device work with a usb2 device without any adverse effect on speed.

A USB 1.1 and a USB 2 Cable are EXACTLY the same.
It will not make a difference in speed.
The only time you will lose speed, is if you are connecting two different speed USB devices.

There may be some slight reduction in speed, but I doubt you'll see much- the older USB 1.1 cables aren't fundamentally any different from USB 2 cables, it's just they weren't tested and verified for throughput at 2.0 speeds (which hadn't been reached back when those cables were made)

USB is designed as graceful degradation, the devices try to communicate at the highest speed possible
if you have a USB type 2 talking to a Type1 then the Type 2 will downgrade to Type 1.
so cable selection shouldn't have that much significance. if both devices are Tyep 2 then the communication protocoal will be Type 2
The cable may theoretically affect communication speed.. but I doubt it... if its reasonably short, has adequate connector pins that are clean then any suitable cable will work. USB cables are usually pretty good at establishing a clean connection.. they have a wipe effect as you connect, so connection quality isnt often compromised by the cable pins

It will most likely have an effect in speed, however i'm not sure how big of a difference. If you're like me, then the minor speed reduction is a better price to pay than buying a new cable.

Differences between USB 1.1 and USB 2.0
USB 1.0 can operate at 1.5 Megabits per second (Mbps).
USB 1.1 allowed a maximum transfer rate of 12Mbits/second. USB mice and keyboards need only 1.5Mbits/s to function. That performance level is also named 'USB'.
USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps. Originally, USB 2.0 was intended to go only as fast as 240Mbps, but then, USB 2.0 Promoter Group increased the speed to 480Mbps in October 1999.
You can use USB device with USB 1.0, USB 1.1 and USB 2.0 as long as your PC or laptop has USB ports, but USB 2.0 device transfer data at 480 Mbps on systems with USB 2.0 support only.
Basically, USB 2.0 includes everything that USB 1.1 offers and adds a high-speed mode, which runs at 480Mbps. USB 1.1 supports two speed modes: 1.5 and 12Mbps whereas USB 2.0 has three of them: 1.5, 12 and 480Mbps. USB 2.0 also uses the same USB 1.1 compliant cables to connect high-speed devices. However, classic USB hubs will slow down USB 2.0 devices. In addition, a USB 2.0 host controller is required to enable the high-speed connection with a USB 2.0 device.

How can I upgrade my USB 1.1 to USB 2.0?
To upgrade the USB 1.1 to USB 2.0, your computer will need to have a PCMCIA slot. (It is also called a PC card slot, which is much easier to say.) The slot is typically located on the side of the computer and is a little over five centimeters wide. It should be covered by a protective flap that will push in when you press on it. You can install a USB 2.0 PC card into this slot, which will give your computer one or more USB 2.0 connections.
As long as your operating system supports USB 2.0, you can install a USB 2.0 card whether or not your computer already has USB 1.1. Note that connecting a USB 2.0 hub or USB 2.0 device to a USB 1.1 port will cause the device to run at the slower USB 1.1 speed. Since USB 2.0 is 30-40 times faster than USB 1.1, it may be worth the upgrade.
Good Luck and Happy Computing..................

i believe there will be a reduction in speed
but not having usb 2 devices i am not sure

the cable themselves dont do much in speed, its the ports themselves. well from what i know
