USB Keylogger Comparison
KeyCarbon products work on every keyboard, as they use an expensive FPGA (Field Programmable Gate Array). Currently, all other other brands of USB keyloggers use cheaper hardware, and thus do not work on some keyboards.
| USB Keylogger Comparison | |||
| Brand | Problem? | Reason? | Rating? |
| KeyCarbon | Brand "KeyCarbon" is compatible with every known USB keyboard. |
KeyCarbon uses an expensive FPGA (Field Programmable Gate Array) chip to interpret USB traffic. This solution works well on all known keyboards. KeyCarbon is firmware upgradable so your unit can be upgraded by downloading an upgrade from the internet. | 100% (good) |
| Brand A (contact us for the exact brand). | Brand "A" does not work if a USB flash drive or any other non-keyboard peripheral is plugged into the USB keyboard. Does not work with certain Logitech wireless keyboards. Does not work on high end Macintosh keyboards. | Brand A uses a USB host/slave chip. This method does not work if any additional devices are plugged into the keyboard. If non-keyboard traffic is detected, it will overload the chip making the keyboard cease to work or behave erratically. | 95% (good) |
| Brand B (contact us for the exact brand). | Brand "B" does not work on 22% of USB keyboards. Does not work on Logitech wireless keyboards or high end Macintosh keyboards. |
Brand B uses a barrel shift chip (1/100th of the cost of a FPGA chip). This method does not work on some keyboards. Has no USB hub chip, so power consumption can result in a "Overcurrent Warning" in Windows XP. | 78% (bad) |
| Brand C | Currently there are no other known brands on the market - email support if this changes and we will update this comparison. | - | - |
