Maybe you ought to order just 1 for testing. I read in the URI write-up that just because it says USB 2.0 doesn't mean that it can keep up the data rate required: "USB hubs are not recommended. However, if a hub must be used, make sure it is rated at USB 2.0 High Speed. Some hubs are USB 2.0 compliant but are rated only at Full Speed (12Mbps) not High Speed (480Mbps). Do not connect any USB 1.x devices to either the same external hub or to the host computer’s internal root hub." Note the docs from the protector web site: Compatibility USB 1.1 (1.5Mbps) / USB 2.0 (12Mbps). Actual speed USB 1.1 (1.5Mbps) You might protect your USB device, but then it might not talk to your computer with this device inserted in the line. Bote

The other option is to hardwire (grounded/bonded/etc) the computer and URI all together with short leads and then put your isolation on the Ethernet side of things. (You could use wireless, but I think that is asking for trouble). Gigabit Ethernet fiber optic media converters are not that expensive on eBay ... I use several of them here. GL Ken

Agree- I saw that the rated speed seemed slow Charlie ________________________________ From: Bote Man <bote_radio@botecomm.com> To: App_rpt-users@ohnosec.org Sent: Tuesday, November 8, 2011 9:10 PM Subject: Re: [App_rpt-users] USB protection Maybe you ought to order just 1 for testing.
